Two houses down from me is a family, a healthy looking family. What I mean by that is there are three boys, two of them are mid-to-late teens and a third younger boy of about 10 years. I often see the three boys walking their dog together, or the two older boys watching the younger one while he skateboards. I never see the siblings argue with one another. It always amazes me. I'm grateful that they apparently live within a family dynamic that has allowed a real brotherly love.
