A conversation with Gabriel in the car, AFTER Krista has left the vehicle for school.
Gabriel: Crusty Krista, Kristy Crusty! (Gramps Laugh)
Me: What? Why are you calling your sister names, that doesn't sound very nice.
G: Kristy Crusty!! (Another Gramps Laugh)
M: Why is she crusty??!
G: BeCAUSE.... sometimes she chews her hair and it gets all crusty. Kristy Crusty!
M: That's mean, don't call your sister names.
G: Well... I can't call her that when she's IN the car. She would get mad at me!
