You will never forget the flavor of this story.

A little boy was holding two apples in his hands.
His dad came and asked with a smile:
“Son, can you give your dad one of your apples?”
The boy looked up to his dad for few seconds, then he suddenly took a quick bite of one apple, and then one bit of the other.
The dad felt the smile on his face freeze. He tried hard not to show his disappointment when his son handed him one of the bitten apples.
The boy looked at his dad with a smile and said:
“Dad, take this one. This is the sweetest apple!”

Postpone your judgment about others.
Give people a chance to explain their actions, even if the action seems very bad in the beginning, because the reason can be very good in the end.
