I was riding in a taxi to the bus station but from there I was supposed to taking a bus to New York City. It was going to be long journey. I had been packed some chocolates in my suitcase to eat in the way. When the ride was over, I paid the driver the due amount and gave him a tip. He got my suitcase out. I took them and started walking away. However, I realized that it was one of the opportunity to perform an act of kindness. I want to give away all the chocolates to the driver. After all, he had served me even though it was just his job. I gave them away and saw the brightly smile light up his face, what made me feel my heart filled with happiness.
