The Mother and The Son (Must Read)

*Once, an old woman was sitting on a bench on a garden with her 25 years old son. 

There was a tree beside the bench. 

The old woman saw a bird sitting on the tree.

She asked the son : what’s this? 
Son replied : it’s a crow.

The old woman again asked what’s this? 
Son said : I already told you that it’s a crow. 

The old woman again asked what’s this? 
Son angrily said : are you deaf or mad, mama? How many times tell you it’s a crow. Can’t you understand?

Old woman patiently replied : my dear son, when you were 5years old, you asked me 174 times the same question that what’s this and I replied everytime with a kiss that, it’s a crow! Now, I asked you 3 times and you were irritated.
