i don't know why i would have a ball. even when i'm at the beach. i'm usually alone. but whatever:
>yeah, uh, that's my ball. i lost it yesterday somewhere around here, and you seem to have found it.
>i don't really need it right now, i don't mind if you play with it with your friends until you're done. but i'd like to have it back later.
if she says no, it's her ball, and i know she's fucking lying, i'd just give her the ball. it looks like a 5 dollar ball, so i don't mind.
