Washing Dishes

I was mowing the lawn today and Kathryn was standing in the doorway, looking outside and watching me ( she is terrified of the lawn mower as well as the vacuum). All of a sudden, I see that she is no longer there, so I go to investigate. I open the door and I see her standing on a chair by the kitchen sink. "Kathryn , what are you doing?", I ask. "Mommy, I am washing the dishes." What do I do? I want to tell her no, but she is only helping, and she saw the need to wash the dishes on her own. It was pretty cute.
