Conversation in the car on the way home from school:
JJ: I was a chameleon today at school.
Me: I know, I saw you.
JJ: I was a male chameleon.
Me: Oh, really?
JJ: Yes. See these bright colors? This is how I attract females.
JJ: I mated with two females today.
Me: …. Oh. Really?
JJ: Yes. With E. and S.
So that’s what they were doing behind the playstructure.
