All that said, now as a parent myself, I feel sorry for him. I consider his childhood and realize he didn't have a chance - he was screwed up from the very beginning. Parenting is darn hard and even if you spent your early years baby-sitting or as a camp counselor or something, it still doesn't prepare you for when they are your own and you have responsibility for them 24x7 from now into eternity. Throw in an unhappy marriage or a failed career and is it any wonder so many parents end up estranged from their children?
So, yeah, the brief article matches my own experiences and those of other people I've spoken with who are estranged from their parents. I think about it regularly, as if I mistreated my children in the same way I can't say I would really blame them for not wanting to associate with me in adulthood when they are able to make that decision for themselves. As my kids have gotten older, I've even made a point to explain to them that every parent is just a human who is mostly winging it trying the best they can -- and that's the thing kids tend to realize, IE: my parent might not have known what to do, but if they showed love and concern, that tends to trump any mistakes.
