That's what she calls herself.
I saw Rob standing outside of Avery's room.
She wanted to read to Ben.
And she wanted to do it by herself so she asked Rob to leave.
This is a new thing. She asks you-usually politely-to please leave her room. I wasn't really expecting that for a few more years.
It was a fleeting moment. Soon Ben grabbed the book and started eating it, then he fell over. Avery lost interest and left to play elsewhere.
But it was a sweet moment.
