After the final examination, my brother and I planned to give us a treat at a restaurant. While waited for our food, we emptied all our small changes from our wallets on the table and counted it out. Soon, our food arrived with note. It reads, “Your lunch has been paid for. Have a lovely meal!” It was a wonderful surprise as nothing like that had ever been happened to us. I remembered an old man sitting nearby. He should have thought we didn’t have enough money to the bill. We looked around to thank him, and he was not there. His kind meant so much to us.
