Once there is a boy lived with his mother. They were very poor and had only a bit of land to make a living by growing grain.
One day, the mother went to the market as usual. She asked if the boy want anything. The boy's eyes went wide with delight. He said: "More than anything else, I want a drum!"

But the left over money after the mother bought necessities wasn't enough to buy a drum. The boy wanted a drum so badly, but there was nothing she could do. However, on the way back home, his mother found a fine stick. It was still better than nothing, right? She was smiling badly while she was handing the gift to her son. The boy decided to not disappointed. Instead of that, he thanks his mother, tapped, slapped, banged on every object with his new stick.

Then he saw his neighbor trying to light her smoked stove. Her eyes watered and she coughed so much. The boy, without hesitation, gave the stick to his neighbor. "Here Auntie, use my stick to heat your stove"- he said. When the stove was OK and hot perfectly, she baked him a soft, round roti, a traditional Indian cake.

The boy was looking for a shade place to ẹnjoy the roti when he heard a baby crying. The baby was hungry but her mother had no food. The boy immediately told the mother to feed her baby his roti. The baby ate the warm, delicious cake. The woman insisted the boy to take a large, metal jug as her gratefulness. What a gift! It dinged like a real drum!

He almost didn't saw someone was groaning from a roadside ditch. An old man wearing torn clothes was laying in the dust. The boy ran as quickly as he could to fill the jug with water. The man drink water from the jug and told his story: "I am a trader, but robbers stole my goods." He just had 2 horses, and they were standing by a tree. The boy also gave water to them. He offered that the trader could took his jug to trade. The old man was thankful so he urge the boy to take one of his horse. "It was a rich gift!" the boy thought.

The boy climbed on the horse and rode happily down the streets. He crossed a group of man sitting under a tree. They were beautifully dressed, unfortunately they looked miserable. The boy asked if there is a problem. One young man said: "I'm going to my wedding, where this band will perform. But if I show up on foot, my bride will laugh at me" The boy hopped off the horse and handed the reins to the groom. He thought that he had a whole life without a horse. The young man needed it more than he did! The musicians leaped up and sang. A singer stopped to thank the boy for his kindness. In exchange, he deserved a beautiful drum.

The boy shouted with joy. He tapped the drum the whole way home. His mother came out to see what the noise was. The boy told her about the story of the stick, a roti, a jug, a horse and a drum.
