Elephant and Tailor

Once a Tailor was friend of an elephant. The elephant used to come daily at tailor's shop and tailor used to give him something to eat. 

One day when the elephant came, the tailor was busy and did not respond to him. After some time the elephant made some noise to gain the attention. The tailor thought of a mischievous plan, he put a needle in his hand and pinched in the trunk of elephant. 

The elephant felt pain and left the place at once. 

The next day elephant came again at tailor's shop. This time he had muddy water filled in his trunk. When he arrived at shop, he spilt all the muddy water in the tailor's shop. All the new dresses of tailor were spoiled. 

The tailor felt ashamed of his bad behaviour, he had learnt his lesson but his true friend was lost now.

Moral: Tit for Tat
