"James, how do you know you're in love?"

I couldn't help it. I fell off my chair. "Bloody hell!" I shrieked as I landed (rather ungracefully) on the wooden floor. I sat up, rubbing my head. Lily was biting her lip in an obvious attempt to keep from laughing.

"Uh…er…what?" I asked stupidly.

"How do you know if you're in love?" she asked again, looking at me tentatively.

"Oh," I said slowly. "Uh, why do you want to know?"

Her face turned red and I instantly regretted asking the question. If my baby sister liked some guy, I most definitely wanted to be kept in the dark about it, so that I didn't do anything crazy, like, oh, I don't know…kill him.

"No reason," she said quickly. "I just…was wondering."

"Well, uh…you want to know about love?" I asked, praying that I'd heard her wrong the first two times she said it.

"Never mind," she muttered uncomfortably, starting to walk away.

"Lily, wait," I called after her. She turned around and walked slowly back to me. "Uh, why didn't you ask mom?"

"And have her tell dad?" she scoffed. "I'm not an idiot James."

"Right…" was all I could think to say. "Well, um…how do you know you're in love…" I trailed off, thinking.

She nodded eagerly, encouraging me to continue.

"Well, I guess you just…know. I mean, when you're around them, you can be yourself, and it hurts when you're away from them. They make you want to be a better person."

She nodded thoughtfully. "Thanks James," she said sincerely. "You've help a lot."

"Uh, Lil?" I asked, grabbing her arm before she could leave again. "This is all hypothetical, right? I mean, you were just curious?"

She smiled. "Sure James," she said.

Bloody hell, why did I do that?

I asked myself the same question a month later when I walked into the Gryffindor common room and saw my baby sister snogging a fifth year.

I slapped my hand over my eyes and groaned. Is this the guy she thinks she's in love with? But he's older than her! Why couldn't she date someone who's a fourth year like her!?

"Aw, bloody hell!" I said loudly, my hand still across my eyes.

"James!" she said quickly. Since she spoke, I decided it was safe to remove my hand from my eyes.

"Hi Lily," I said rather uncomfortably. "Whatcha doin'?"

"Homework," she replied, a little too quickly. "Oliver here was helping me with my homework."

"Oh," I said, nodding my head. "Well, uh, I'll, er, leave you to it then…" I trailed off, walking up the stairs to the boys' dormitory.

But not before I heard Lily say, "That went great! He didn't even hex you!"
