Molly draws

I love how she still hums while drawing. Molly hums when she is concentrating, when she is happily playing by herself, and when she is drawing. I think she does it when she is in flow. She seems relatively oblivious that she's doing it.  Some people say that they think she'll quit when she goes to school, but I suspect that in moments of focus when alone as an adult, she'll catch herself humming.
