You had your sweet 16? hahahaha are you a girl? You have to be. Guys dont have a sweet 16...
What a dumb bitch. I would have been like "Look, its my B-Day, Im having people over. Its called a b day party. Bye for now" then you hang up and if she calls dont answer. If she wants to come by, let her come by and take her son home. He is causin problems, well his mom is. I had the same problem at a party once. Kicked the bitch right out no question. And said go with Daddy. But we were drinkin and smokin but it was outside.
