Some of your sons may come home and seem like they are crazy. They are not. All they want to do is climb a tree (or do anything risky), wrestle in the grass, and be the hero. They spend their whole day at school where there are no trees, they aren't allowed to take risks, and they are told to never question authority. Three of my kids will be fine. The other one can't be contained. It's my job to make sure he goes to school with enough padding, so that the walls around him don't hurt too much, as he bashes against them.
