    A son took his old father to a restaurant for an evening dinner. The father was very old and weak. While the father was eating, he dropped food on his shirt and trousers, and also on the table, the chair and the floor. Other diners watched him in disgust (厌恶) while his son was so calm.

After the father finished eating, the son who was not at all embarrassed (窘迫，尴尬), quietly took him to the washroom, cleaned his clothes, smoothed his hair and fitted his glasses firmly. When they came out, the whole restaurant was watching them in dead silence, not able to understand how someone could embarrass themselves in public like that. Without saying anything or watching at anybody, the son walled directly to the counter (前台), settled the bill and started walking out with his father.

At that time, an old woman among the diners called out to the son and asked him, "Don't you think you have left something behind?"

The son replied, "No, madam, I haven't."

The old woman repeated, "Yes, you have! You left a lessons for every son and every father." The restaurant went silent.
