Once there was this pool party at my girlfriend's house. The whole grade was invited (50 people to a grade, tiny charter school) but only about 30 showed up.
Anyhoo, everyone was scattered around the house doing whatever, when someone yelled "Ok, we're gonna go outside and swim". Each guy (only about 10 of them) took turns going into this one bathroom to change and such. The first guy went in, when my friends and I saw a hilarious sight:
My girlfriend's room only had one small closet, where a person could hardly squeeze through, let alone change. Anyway, all of the girls go into her room with her.
About 3 minutes later, they all come out in bikinis. My friends and I had to keep from laughing for the next 5 minutes.
After the party, I asked my girlfriend about it. She said "well, we're all girls, and we all have the same stuff going on (if you know what I mean) and we all changed in the same room."
True story.
Just goes to show that women do a LOT of stuff together.
