A son takes his old father to a restaurant for dinner. They sit down and order a meal(点餐). The man orders some rice and vegetables with chicken. His father likes jiaozi very much, so he orders some jiaozi for his father. His father is very old and he doesn't look healthy. Some food is on his T-shirt or pants(裤子)after eating. Some people in the restaurant don't look happy about him when they see him eating food. But the son doesn't care (关心) at all.
When the son gives the waiter money, the waiter says, "Oh, the dinner is free."
The son asks, "Why?"
A young man is next to the waiter and says, "Sir, I'm the boss (老板) of this restaurant. I think you're a great man. You love your father very much, right? I learn a lot from you." The son says, "Yes, you are right. But what do you learn from me?" The boss says, "A lesson (课) for every son and hope (希望) for every old father."
