Gee, life moves on, doesn't it.
For someone who grew up in the sixties when there were vastly more changes going on than I have seen since, we all came out of it OK. We all wore shoulder length hair, beads and cheese cloth shirts, smoked the wrong sort of cigarettes, listened to music that called for a revolution in ideas, raged against authority, wanted more sex, less listening to 'the man'...it went on and on. But we all came out of it ok. Primarily in my case because my parents rolled their eyes and gritted their teeth and relied on me to have understood the basic sense of morality that they had taught me.
To be honest, after all that, what kids are going through these days seems almost a little tame. Nothing mine did exceeded anything I did. And in most cases weren't half as bad. The differences between myself and my kids were negligible compared to those between me and my father. He simply didn't understand. I guess I understood better when it came to my two. So we all grew together as friends eventually as well as parents and children. We all see each other regularly - and I mean a couple of times a week socially at least. Lucky? I guess.
But that's what people should be aiming for - getting close to your children whilst still allowing them as much freedom as possible. Even if in my case it was perhaps more luck than judgement. Then a lot of these problems become less of a problem for the child. And more a problem to be solved by the family.
