When they were teenagers, my two sons joined the local sports club where they played tennis, hockey, cricket and, in the evening, were able to play snooker and darts. I assumed that they would be safely under the supervision of responsible adults. Thirty years later, I am regaled with tales of under-age drinking and my younger son being the club champion at downing a pint of ale in the shortest time. How they ever grew up to be, themselves, responsible parents, I can't imagine. I don't think I was the greatest role model and my ex had walked out when they were just young teenagers and wasn't around.
