A child will have many friends, but only two parents—if that—and parents are more, not less, than friends. Friends have very limited authority to correct. Every parent therefore needs to learn to tolerate the momentary anger or even hatred directed towards them by their children, after necessary corrective action has been taken, as the capacity of children to perceive or care about long-term consequences is very limited. Parents are the arbiters of society. They teach children how to behave so that other people will be able to interact meaningfully and productively with them.
