Serves me right for asking.
Me: What's going on up here?
The middle: Nothing. Well, apparently I made The Baby feel guilty by telling her that Nanny said she misses her and is sorry she couldn't make it to visit.
Me: Oh... huh. Well, I'm sure she said the same about me. I don't feel guilty. I just couldn't be there because of the party.
The middle: Actually, she wants you to know that she doesn't miss you, you're a bitch and she never wants to see you again.
