The old man told his son everything. As a daughter-in-law, even if he is right, he may make mistakes. How should I face it?

Find an obvious and correct example to tell your lover that you are wrong, and then show generously that you don't care about the confusion of the old people sometimes, gain the understanding of your lover, and be more tolerant of the excessive behavior of the old people sometimes. Old children are numb, and old people sometimes need to be coaxed like children. I wish your family happiness and harmony!
