This morning Emma and Macey were in a loud dispute over a toy. I think that Macey had it first but Emma wanted it. There were some words exchanged. And then some louder words. And finally the situation came to blows.
Macey ran over and cried to me that Emma had hit her.
"Emma," I said, "Please do not hit your sister."
"Oh, okay Mom," she answered.
And I thought to myself, why did she answer as if that was a whole new rule she had never even heard of but was willing to give a try?
