It's was Piper's seventeenth birthday. For once, she decided to throw a pool party. Not just the usually get- together we usually had every year as friends, but a massive one. I think she invited the entire school. She hired a DJ and caterers. Her house could handle that kind of a thing. Just outside there a court for sports, a huge swimming pool with a diving board, slide, and cave, a fire pit, and several comfy cabanas and places to lounge around. But out of everything I could do, I still wanted to find my best friend. We hadn't talked about her mother's party, but it was still bugging me at the back of my mind. I saw Annabeth on a hammock tied between two trees. She was reading, of course. She looked engrossed in her book, so I decided to leave her in peace and look around the place. Besides, Piper was kicking everyone out at midnight so we could still have our group sleepover.

It wasn't like I hadn't been to Piper's house before, but it was gigantic; I didn't think I would ever completely explore the whole thing. I said hi to a few people I knew from school before heading over to wish Piper a happy birthday.

"Finally decided on the big one, huh Pipes?" I state.

She spun around. "Percy! Hello. Oh yeah, my dad said I should" she deepened her voice, "have a more social outing and help others to achieve the 'teenage dream'. Then he went on singing Katy Perry."

I laughed, "Well I would definitely count on this as a "social outing." Oh and happy birthday, by the way."

"Thanks." she replied, "So where's Annabeth?"

"What? Why would you think I knew where she was?" I lied.

"Because it's Annabeth." she gave me a knowing smirk.

"Oh and what about Jason?" I asked. Its about time the two of you get together." I said.

"Shut up."

"Oh and she's reading in the hammock." I replied.

"I am?" came a voice from behind me.

"Annabeth!" Piper called, then gave her a look that said 'You came to my party and were reading even before you said hello.'

"Sorry, I was almost done. And now I am!" she beamed, holding up her book. "Oh and you and Jason-"

"Okay! Well now that you are finished, let's go have fun!" Piper cut her off and dragged the two of us over to our friends at the volleyball court.

Two and a half games later, we were hot and sweaty.

"Let's go jump in the pool," I heard Jason, Piper's best friend, suggest. It was the best idea ever. Everyone had worn a swimsuit, because it was a pool party. And there was plenty of room for all to swim. Several of the guys were doing tricks of the diving board, trying to impress the girls.

"Hey Annabeth." I called. "You look a little hot to me." I picked her up and carried her over to the pool while she was screaming, "Percy! PERCY DON'T YOU DARE! PERCY JACKS-" and I dumped her into the pool.

I stood there laughing for a full dive minutes. It didn't help my case when Annabeth came out dripping wet and storming mad. It was hard for her to look too mad when I was laughing and her conflicted expression just made me laugh harder.

I was still chuckling as I heard Jason call my name from the pool. I was about to respond when I felt someone push me from behind and I fell into the pool. Now it was Annabeth's turn to laugh. She must have told Jason to call me over so she could push me in.

"Yes, ha ha ha revenge on Percy." I uttered. "Okay!" I yelled, "Boys vs. girls squirt gun fight! Go!"

Everyone was running around and screaming, water was coming from every direction. It was really a blast because there were so many people there. The game ended when Piper had Jason cornered, weaponless. Since they were the captains of the opposing team. He put his hands up in surrender. "Alright, you win," He called. Piper held up her gun in victory and the girls cheered.

"Good game." Jason said right before he kissed Piper full on the mouth.

Everything went silent, then we all cheered. Seriously, it was so obvious they liked each other. And I was a guy. It was about time.

"Finally!" someone yelled and we all laughed.

The DJ announced that the dance floor, which was actually a large section of patio, was ready. A slow song started playing and a whole bunch of people ran over, including Piper and Jason.

"Lovebirds." I smirked.

"So when's that happening with you and Annabeth." a girl named Silena said.

"Woah, we're just friends."

"Mmm hmm. I can always tell with these sorts of things." she walked away smirking. And yeah I wished she was right.

A few hours later... it was a few minutes till midnight. Piper started announcing the party was over. People slowly left and by 12, everyone was gone except for our group of friends.

"Okay, let's get our sleeping bags rolled out on the lawn." Piper called. "Then we can go for a night swim."

She grabbed Jason's hand and went to get their stuff. Everyone was setting their sleeping bags up, bit I had a heavy feeling weighing me down. I realized I was jealous. Jealous of the relationship that had come so easily between Piper and Jason. And that I was still wishing for that relationship with Annabeth.
