Since I can remember, my grandfather has always been trying to please my grandmother.,I sneakily asked my grandfather, "You get up early every day to cook, three meals a day, and then you go to work. You do this every day, even on legal holidays. Don't you ever get tired",It's not because I'm afraid of my grandmother, but because my grandfather favors her. This is common knowledge in the family.。
