On the way home from church last night:
Girl Child: Mom? What's the worst thing you can say to a boy?
Me: *dying of hysterical laughter*
Boy Child: I know!
Me: *wiping tears away*
BC: I know what it is, Girl Child!
GC: What? No, really. What?
Me: I'm sorry. I can't tell you.
GC: Mom! What is it?
Me: I'm sorry, I just can't tell you.
GC: Are we too young for this?
Me: Yes. And you will be. FOREVER.
BC, smugly: I'm a boy. I know what it is.
Me: What do you think it is?
BC: I'm not going to say. But it involves bananas.
Me: *pulling off the road so I don't wreck the car because I'm laughing so hard*
