im going to be 16 in about a month, and im inviting around 20 girls to my house. its going to be in the evening so most things outside cant be done, and i dont want to go anywhere for it- it should be indoors. we are hiring a lady to do henna tattoos, so that will be about an hour, but i dont have any games or anything to play after that! i cant do a scavanger hunt cuz i've already done that, so do u know any fun games or activities 20 teenage girls can do?!?!?!
