Brushing War

My kids have straight, fine hair, so it looks pretty messy when they forget to brush it. One morning Megan was looking especially stringy, so I reminded her to go brush her hair. She ran upstairs and came back claiming she had brushed it but it looked just the same. I sent her upstairs to brush it again, but once again she came back stringy with the claim that she really brushed it--again.
Exasperated, I said, "What are brushing it with?" Megan proudly responded, "My fingers."
