This is empathy...

A boy went to the pet store to buy a puppy. Four of them were sitting together, priced at Rs. 5000 each. Then there was one sitting alone in a corner. 

The boy asked if that was from the same litter, if it was for sale, and why it was sitting alone. The store owner replied that it was from the same litter, it was a deformed one, and not for sale. The boy asked what the deformity was. 

The store owner replied that the puppy was born without a hip socket and had a leg missing. The boy asked, "What will you do with this one?" The reply was it would be put to sleep. The boy asked if he could play with that puppy. 

The store owner said, "Sure." The boy picked the puppy up and the puppy licked him on the ear. Instantly the boy decided that was the puppy he wanted to buy. The store owner said "That is not for sale!" The boy insisted. 
The store owner agreed. 

The boy pulled out RS. 200 from his pocket and ran to get RS. 4800 from his mother. As he reached the door the store owner shouted after him, "I don't understand why you would pay full money for this one when you could buy a good one for the same price." The boy didn't say a word. He just lifted his left trouser leg and he was wearing a brace. The pet store owner said, "I understand. Go ahead, take this one."
