A son took his father to a restaurant for dinner. Father being very old and weak, while eating, dropped food on his shirt and trousers. Other diners watched him in disgust while his son was calm.
After he finished eating his son who was not embarrassed, quietly took him to washroom, wiped the food particles, removed the stains, combed his hair and fitted his spectacles firmly. When they came out, the entire restaurant was watching them in dead silence, not able to grasp how some could embarrass themselves publicly like that. The son settled the bill and started walking out with his father.
At that time an old man amongst the diner called out to the son and asked him, “Don’t you think you have left something behind?”
The son replied, “No sir, I haven’t“. The old man retorted,” yes, you have! You left a lesson for every son and hope for every father. The restaurant went silent.
