A son took his old father to a restaurant for an evening 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 at all embarrassed
quietly took him to the wash room, 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 someone 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 diners 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.
