Mating...

We're at the butterfly pavilion and Caleb turns to me and points out 2 butterflies that keep following eachother.
Caleb - "see those 2 butterflies that keep going around each other?  They're mating!
Me - Really?  What do you mean by 'mating'?
Caleb - You know!  Like, they're going to get married. (long, contemplative pause...)

OR GET INTO A REALLY BIG FIGHT OR SOMETHING!"

I had to bite my tongue to keep from laughing.  The irony is how right he is!
Out of the mouths of children!
