Ok, These are my best ideas to have a great pool party and sleepover \*Did this for my birthday\* The first thing I say is make sure you're going to have fun! What we did was invited everyone over, played some board games until everyone arrived when they all came we went swimming because it was REALLY hot out. In the pool we played a whole bunch of games \*races, Marco Polo, ect.\* We had a blast! We even did some competitions. The next thing we did was set out the snacks \*chips, candy etc.\* Everyone has to eat! You can't forget the drinks and food!! The second thing I say is don't get too carried away.  We have a trampoline so EVERYONE wanted to go on. But the max is only 3 people and there must have been 25 of us! So in that situation you have to keep your cool. Make sure everyone gets a chance, and don't go crazy if someone gets on longer than you. The third thing I say is relax, just a party, go just enough to the XTreme so no one gets mad. We decided to play a little prank on someone. You Know, It's a party, not gonna last forever, and hey, you gotta live your life and take it when the opportunity comes around.  Me and my friend Matthew  filled one of our friends shoes with water \*Konrads\* The sun was out we were looking for something to do when we saw them. HE wouldn't mind,, it's only a silly prank. So when he stepped in them, he just said "What?..ohhhhhhh....kkkkkkk....." He had no idea it was us. When we started laughing he's like " It was YOU!" and we cracked up even more. After that we had a HUGE water fight! it was awesome! We had one person on the treehouse throwing balloons 4 people guarding our base and the last 3 with water guns.it was 5 vs 5 cus the others wanted to stay in the pool. The point of the game was to get the other teams flag \*capture the flag\* with water fight it was so cool!!!!!!!!! everyone had tons of fun. So anyways to top it off we added the cherry to the ice-cream. =] It was a sleepover as well so we got out sleeping bags, hauled them downstairs, got a flashlight and shut off ALL the lights. it was pitch black. Couldn't see a thing. So I turned on the flashlight and brought it under ym face. You know, to make it look freaky. " Ready To Begin? " I asked. And that was Ghost story time. We stayed up all night playing games and telling stories. Now THAT'S what I call a cool party!!!
