You know me and know that I am NOT uptight about things.......but even with your daughters being the age that they are, I wouldn't do it..........
Times are different and you could be sued and even arrested for this if anyone complained........ I would tell the girls to have the party, but no alcohol........if someone happens to sneak it in and you are not aware, then that is out of your control...........
Let's say I decide to let them have their party. What would happen to the adults if it was to get out of control? And the 'adult' friends? I'm seriously going to say no, but I want to cover all the topics. Plus, since my kids are smart and savvy, 'because I said so' doesn't cut it anymore. hahahaha.
