It's important to be honest with and respectful of each other and deal with issues as they arrive, as opposed to letting them simmer.
I believe what really happens in history is this: the old man is always wrong; and the young people are always wrong about what is wrong with him. The practical form it takes is this: that, while the old man may stand by some stupid custom, the young man always attacks it with some theory that turns out to be equally stupid.
