well, parents lol. Sometimes it's like somebody else's parents give money for all of us, then for instance my parents do that, or other times they give money to each of us separately, OR in a girl's case, it's also guys who pay. Especially if he has a crush on you he's gonna pay as much as you want so we usually take guys with us it's more fun that way too. Or start alone and then when we run out of money we invite them :D (yea, and some girls including me openly say-- don't come unless you have money, they take no offence tho.. and my friens like that about me they say i can be a bitch in a good way lol) I dunno where THEY take there money from, but they always have it lol.
