What will you do when you meet an old man who is completely unreasonable?

My grandfather is a man who does nothing without reason. After all, the old man is old. If you want to maintain a harmonious family life, you must tolerate and respect the elderly. After all, he is also an elder. It is impossible to be tit-for-tat like young people! Old people are not easy. When they are old, they should not be provoked. People like a quiet life when they are old! Such a noise must be avoided! In this case, the family is very helpless and has a special headache when it happens. This kind of old people who are not sensible generally have a big temper. If they are not careful, they may have a little problem. You may be hospitalized by young people! So enough is enough!
