If that's your only comeback, I can't help but pity your immaturity.
I'm sorry that I stopped thinking shit like that was funny in the 2nd grade.
There's going to be a time when you both need to grow up.
Seeing as how it hasn't happened yet makes me wonder how bad your father molested you, or the fact that your mom still lets you play with your sisters barbies.
My prayers go out to you.
