Baldness, from a child's eyes

On the playground afterschool, the father of one of the kids came to pick him up. Usually the mother arrives for him, so he wanted to meet some of his son's new friends. They called over one of his son's closest buddies in class, and he comes running across the playground to say hello. Without introducing himself, saying hello, or talking to his friend, he looks straight at the father and states "You have very little hair!" The father had to agree.
