Lily was a pain in the arse.

From the time we had left the Great Hall, she had managed to drag me down a number of corridors, push me through the entrance to her common room, up a flight of stairs and through the door to her dorm.

The second I walked through the door, I dumped my bag by it, before removing my robe and dropping it on top.

I was going to leave it in my dorm but decide against it, especially when firewhiskey is involved.

Not long ago, Lily and I deducted that when firewhiskey is involved, we always end up playing truth or dare.

So I brought my robes, mainly as a precaution, because when we end up playing it, she always makes me go wandering round the cold castle in the dead of night, and I don't fancy getting detention for waking up a portrait due to a sneezing fit.

I shuddered at the thought and kicked my shoes off onto the pile too.

Under my robes, I always wore the same thing due to the schools uniform rules; it was a simple oxford blouse with a black skirt that came just above my knee and my Ravenclaw tie. I always wore tights and a jumper too, but thanks to the weather, and the fact it wasn't extremely cold, my tights were of a low denier and my jumper was sleeveless.

I looked at Lily; she was now sprawled out on the floor in the middle of the room with her eyes closed. She momentarily opened them to check I was clear of the door, before she pointed her wand at it and muttered something. I looked to the door when I heard the lock click, and when I glanced at her again, her eyes were once again closed.

She looked the picture of innocence and modesty, lay on her back, arms out to the sides, eyes closed but we both knew different.

She loved having a famous father, and when you have two brothers, being the only daughter of Harry Potter has its perks.

The main one was that she was looked up to by a lot of younger students, if they didn't want her, they wanted to be her.

Her looks, her personality and her persuasive charm, they wanted all of it.

I know this because of how she got a dorm room to herself. One day she thought that she deserved one and by using her charms, status and a couple of threats, she got a group of third year girls to move into other dorms so she could have a room to herself.

I threw myself onto her bed and looked at her. She was staring straight at me.

"Girl, you suck!"

I rolled my eyes at her.

"What do you mean, I suck?" I asked, filling my voice with question.

Lily suddenly stopped staring at me and had taken a sudden interest in her nails.

"I mean nothing, I'm just telling you that you do," she said in a voice that implied that she was completely bored by the conversation. She looked up at me again, changing the subject, and her tone, "hmm, I think my nails need redoing, but not before we've cracked open the firewhiskey, eaten our body weight in chocolate, and slagged everyone we know off."

"Agreed!" I laughed as Lily rolled over, pushed herself onto all fours and crawled to my pile of things by the door.

When she got there, she stood up and picked up my bag, before walking to the bed.

I moved so that I was sitting near the headboard with my legs crossed beneath me.

When she reached the bed, Lily opened the bag and proceeded to empty the contents onto the bed and found exactly what she was after.

Lily pulled the firewhiskey from the nest of clothes I had made it when I packed the bag, and walked to the dresser on the other side of the room, before pulling two glasses from the top drawer.

Lily turned around and walked back to the center of the room, where she swiftly sat down on the floor and placed everything in front of her.

I got off the bed. I knew what this meant.

When Lily wanted to sit on the floor and drink, she wanted us both to get drunk and spill our problems to each other. She didn't do it often but when something big came up, if was her way of saying 'I need to talk about something that I can talk to no one else about.'

I sat opposite her and she unscrewed the lid of the bottle, pouring us both generous measures of the ruby coloured liquor.

Lily resealed the bottle, replacing the bottle on the floor, and pushed a glass towards me with her left hand.

Her right hand was around the other glass, her glass. She raised it to her lips and took a large gulp.

I saw her wince at the stinging heat of it hitting the back of her throat before she smiled at the warm feeling that she got in her stomach.

It was like someone had flicked a switch in Lily's head. And once the floodgates had opened, there was going to be no stopping her talking.

I heard Lily take a deep breath and then she began.

"Albus sent mum and dad a letter telling them that I had been seeing a guy from beauxbatons, and that I was 'the other woman' in the relationship. Anyway, I got a demanding letter from mum today, explaining to me what third parties in relationships do, and how neither couple survive from them. And then she told me that I did not explain everything, that I would be cleaning the house from top to bottom all Christmas."

The look in her eyes was dark from remembering it. I thought some input from me might help her.

"Well, that was very, Slytherin, of him." I said raising my eyebrow at her, before lifting my glass to my lips to sip it.

She took another gulp and carried on talking.

"I know! Anyway when you saw me earlier, I had been to the owlery to send a letter home, explaining that when I had been in contact with Pierre since he went back to France, but when he told me that he had a girlfriend, that was when I cut him off, and that I haven't spoken to him since. I don't know why Albus has to take it into his own hands and be such a grass."

I laughed. "Well Lily, he is a Slytherin, and that is what he will always be. Forever acting sly and undermining people, because that's all they know. Really Lily, when have you ever known a brave Slytherin?"

Lily took another large drink of firewhiskey, and laughed.

"Ahaaa, that's truer than you think, babe. That's truer than you think."

This confused me, but I brushed the comment aside, leaning over to the bed to grab the chocolate from my belongings.

I broke off a huge piece of chocolate and started to eat it. I passed the bar to Lily. She took it off me and did the same.

I heard Lily's voice again.

"So, did anything happen to you today since I saw you at lunch?"

And then it all came flooding back to me, and how Harriet Bell had questioned me about my cousin, and Scorpius.

I took a large gulp from my firewhiskey now, feeling the burn in my throat and then the warmth in my stomach.

I did it again to steady my nerves, which it did, and as I began to talk, Lily began to drain her glass.

"Well Lily, potions was potions, as usual. However it was after potions that was interesting, because I got to my dorm and that stupid third year, Harriet Bell came to see me. For some stupid reason, she had dragged her friend Charlotte Zabini with her too. So anyway, Harriet was like 'oh, can you get me a date with Albus or Scorpius or Louis, please?' It was mega annoying, so I told her straight that I don't know or care for my relatives' agendas and that I wasn't going to help her, before I stormed out and found you in the corridor."

Lily's hand flew to her mouth to stop her spitting her drink out on me.

I heard her swallow loudly before bursting out into a fit of laughter.

Seeing this, I started to laugh too.

After 15 minutes of pure laughter, Lily regained her speech.

"I can't believe it Rose! She always seemed like such a stuck up cow, and now we know that for sure!" She caught my eye and giggled inappropriately before carrying on. "How did you manage to remain so calm?"

I finished my drink and raised my eyebrow at her.

"Lily, do you really class that as calm, because I seriously don't."

She chuckled darkly, and gave me a tipsy smile, the mischief playing across her face.

"Babe, that was calm, cause if it was me, I woulda bitch slapped tha hoe into next week, and then gone all 'hardcore dark lord' on her sorry ass. I bet she would of lurved that!"

I was chuckling now. Lily was pulling one of her faces and her accent was just as funny.

Then she suddenly leaned on her bed and pulled herself up so she was standing. Lily looked pretty steady on her feet, especially as she walked towards her dresser.

When Lily reached her dresser she opened the bottom drawer and pulled out a pair of men's light-blue boxer shorts and a grey vest top.

Blue boxer shorts? The only person I could think of that might own blue boxers, were Pierre. I had to ask her about them.

"Lily, are those Pierre's boxer shorts?" I had tried to sound innocent, but the laughter I was trying to mask in my voice was obvious.

She turned her head to me, blushing.

"Umm, yeah, they are," she said shutting the drawer in her dresser and making her way back to me. She wasn't finished speaking though. "I only got hold of them by accident though. I was dared to take them and then I kind of forgot to give them back."

I let a giggle slip from my lips. Lily ignored it and kept talking.

"And they're not half comfy to sleep in though." She said, followed by a wink.

I giggled at her again.

Lily walked to the bed and picked up my jogging bottoms and vest that she tipped on there out of my bag when she was hunting for the firewhiskey.

They then swiftly hit me up the side of the head.

She might be merry, but Lily Potter could still throw straight.

"Go get changed," Lily instructed me, unlocking the door with her wand. "I think this is going to be a very long night."
