Crab, I agree. I am the father of sons. In their teenage years, in particular, it seems that they have found the boundaries imposed by myself and their mother to be a comfort blanket and a place to tie up against in a storm (not that they would admit it at the time). I was the same with my parents.
It appears that some of their friends and aquaintances, for various reasons, don't initially have these boundaries laid out and have found the transition towards adulthood rather more difficult.
Perhaps most folk eventually come to find more or less the same boundaries but the ones who are shown them earlier don't fall foul of the umpires so often in the process.
