It is a curious fact that small boys are more terrified of their babysitters than small girls are. In part, this is because small girls and babysitters, who are usually slightly larger girls, belong to the same species, and therefore understand each other. Small boys, on the other hand, do not understand girls, and therefore being looked after by one is a little like a hamster being looked after by a shark. If you are a small boy, it may be some consolation to you to know that even large boys do not understand girls, and girls, by and large, do not understand boys. This makes adult life very interesting.
