A friend of mine called Chris ( ex miner ) had a highly charged teenage son, who was causing a lot of problems. One day his wife rang him and explained the son was playing up, so Chris went home and gave his son a good beating.
The outcome was his son thanked him many years later, saying that if his father had not taken that stern action he would most certainly have finished up in prison, instead of the good person he grew up to be.
Would this be applicable to all children I think not, as all children are different.
