(One day's conversation about marriage)

Clem: I'm going to marry Eleanor.

Me: You can't really marry your sister. You can marry a friend, someone from your school, but not your sister.

Clem: Maybe I'll marry Avery Joy then.

(Another day's conversation about marriage)

Clem: But I can't marry a boy.

Me: You can marry a boy if you want to. Sometimes girls marry girls or boys marry boys.

Clem: (thinking)

Me: What about our friends Tana and Holly. They're married.

Clem: But then they can't dance!

Me: Sure they can! People can dance with whomever they want to!

Clem: Oh. Okay.
