(My five year old son): Mom, I'm gay.
Me: Really? So you want to marry boys?
Son: No, I like girls.
Me: Sweetie, then you aren't gay. That means boys who love boys, and girls who love girls. You are heterosexual.
Son: Look mom, I just wanna be gay but marry a girl!
Me: ... Well I guess that's how some gay guys do it...
