When parents are old enough to quarrel, they can let one of them live in their children's house and say that it is to help with housework. In fact, it is to keep them at a distance, because the old couple are too familiar. When we meet less in the future, the two sides will be more polite when they get together again, and they will talk less and stop talking, so that the relationship will be eased and the problem will not be solved by quarreling.
