He came home from work, tired. He sat down on the sofa and put his feet up

He came home from work, tired. He sat down on the sofa and put his feet up. His wife brought him a glass of water. His son gave him a sheet of paper and he read through:
English 17%
Biology 35%
Mathematics 40%
Physics 37%
Chemistry 42%
Economics 12%

Agriculture. 19%
Geography 22%
Suddenly, he lost his temper and started shouting: “What is this? All the time you are on phone and TV! How dare you bring me such marks? How dare you?”
His wife said: “Be patient. Listen….” But he interjected,”Shut up! It’s your love and pampering that has spoilt him. He is no good and never serious at all!”
His Wife said: “Oh,really?”
He shouted: “No one in our family has performed so badly,ever!”
The son said: “Dad, I am sorry I made you angry. I was cleaning the old cupboard and I found this. It is your old school report card, dated 27th July, 1980 sir.”
The man became humbled and dumbfounded. Imagine the atmosphere afterwards. Calmness in the air. With a foolish grin on his face,he replied, “Son,you don’t know. Those days food was scarce.” ??‍♀

*MORAL OF THE STORY*
” Let every one be swift to hear, slow to speak and slow to anger.”
