Once a farmer owned a horse and a donkey. Horse used to carry master and donkey used to carry his loads. One day, farmer went to market and did a lot of shopping. After shopping was over, farmer loaded all the supplies on donkey. It was too much for donkey to carry. Therefore, donkey asked horse, "My dear friend, this load is too much for me to carry and will not be able to carry all this load back to home. please take some of it on your back."Horse arrogantly refused saying,"It's your duty to carry loads. mine is just to carry master not all this load."Donkey managed to carry load for some distance but then he collapsed. Farmer saw collapsed donkey and shifted whole load from donkey to horse. Now horse thought to himself, "If I had accepted the donkey's suggestion, I would have to carry just half the load."
