The son takes his old father to a restaurant and eats with him. The father would wake up awkwardly with a spoon and eat his food on the table and on his clothes, and the people at the nearby table, who saw this, would frown suspiciously and look at his son, who would calmly eat without paying any attention. After the meal, the son gets up, cleans up the spills, takes his father to the bathroom, cleans the stains on his clothes, combs his hair, and comes out. Seeing this, the father said, "My son, don't you think we are leaving something here?" "No, father, nothing was left." The father said loudly, "No, my son, we have left here a lesson for the boys, but for the fathers to believe in the future." Everyone looked down in shame. Yes, we, the people who raised ourselves to take care of ourselves, should we be ashamed to take care of them in their old age? It is our duty to love and take care of our beloved grandmothers, grandfathers, fathers and mothers in old age, and we notice that our young teenagers make such mistakes. I wanted to deliver.
