Someone has been listening too closely to Mommy's medical problems.

Moira: I have an itch!
Me: Oh, yeah? Do you need help scratching it?
Moira: No, I did it all by myself, but I think I have to go to the Doctor later.
And about every 2 minutes since then she'll just say "Yeah, I have to go to the Doctor later". Note to self, stop complaining!
