Tonight you helped me wash the dishes. And you were darn good at it! I was getting dinner ready and washing up a few that were still in the sink. You stopped playing cars and insisted that you had to help me. Sweet. I imagine you won't be nearly as enamored of cleaning when you're 15.
Later, we had a small disagreement when getting ready for bed. You have a difficult time focusing sometimes. To the point that you don't always pay attention when Mommy and Daddy are asking you to do something. So when you ignored me three times, I had to put you in your room for a minute to think about things.
As I was walking away, I heard you grumble: "I don't like my mommy! She is a vehicle. Made of grass."
Hee!
