Daughter 2 and I sharing a toilet stall:
Daughter 2: Momma, when do you think I'll get my period?
Me: It'll be a few years, I'm sure. But no one really knows exactly when she'll get her first period.
Daughter 2: Oh. I just don't want it to be a surprise.
Me: Well, I'm pretty sure your first period will be a surprise.
Daughter 2: Actually, let's talk about something else.
Me: Okay. What do you want to talk about?
Daughter 2: Actually, I just realized that a toilet is not a fun place to have a conversation at all. Let's just enjoy the silence. And the tinkling.
