Matilda - I need to get in the tub and soak my back.
Me - (Laughing) What happened to your back?
Matilda - It is SO sore.
Scene 2: Lounging in the living room, mid-day.
Matilda - I'm lying on the couch and resting my back.
Me - Oh, is your back feeling sore?
Matilda - Yeah, it's sore. I was eating a lot of snacks.
Me - Did the snacks make your back sore?
Matilda - Yeah!
(I have no idea why she thinks excess snacking would lead to sore-pregnant-lady back. Regardless, it seems she's heard enough of my complaining.)
