One of us is mature. The other is a mom.

Ethan: In a book in school, there's a picture of a boy completely naked.
Me: *shrug* You know what a naked boy looks like.
Ethan: Yeah, but I think that's completely inappropriate for school.

And this is where it would have ended, if it were up to me. But no.

Ethan: Some boys in my class were looking at it.
Me, trying to keep this conversation from turning into an interrogation: Where did this book come from?
Ethan: It came from Ms. {teacher's name redacted}'s room.
Me: And what was going on in the book?
Ethan: I don't know, I wasn't reading it. The boy was just standing there. Facing forward.

And before anyone asks, no, I did not complain/express concern to the school- for lots of reasons. For one, I am so not concerned- didn't want the conversation in the first place. For two, possibly Ethan misinterpreted it. For three, every kid is curious, it's no big deal.

For four? *At worst, I am not going to be the one outing little boys.

*Why, yes. Yes, that was a joke. Glad you recognized it.
