The world we live in. It is natural for parents to take care of their own children. They take great trouble to feed and clothe them and are over-anxious to give them a good start in life.
Most children take advantage of their parents.
Some get into a lot of trouble and have to be taught to behave better. However, we cannot pretend that adults are good. We only have to follow the news to be reminded of all the violence and corruption in the world. We hear about countries which are trying to prove superior to neighbouring states by attacking them and sometimes they succeed in obtaining control of them. We read about boxers who fell their opponents with brutal punches causing them to fall in front of an audience of excited spectators.
