Rachel went to sleep around 7:30, woke up at 10:30 pm and then apparently stayed up all night long working on her play. So today, she's having a little trouble. She just bumped something and said "Ow. (pause) I know. I didn't sleep enough so I'm tired. And that makes me cranky and hurt myself. And that makes me act like a little girl. Which makes you treat me like a little girl. That's the 'Little Girl Chain Reaction.'"
That is exciting progress to witness.
