Last night, I was waiting for a taxi. After 5 minutes, I was 36 . The driver seemed to be angry. I asked him what the 37 was. He said he had just come from the airport without a 38 , which was basically $70 in lost fare. Over the course of the ride, the anger 39 died down. He mentioned he had read an article saying the 40 people are the ones that give, so he hoped he’d have more 41 to give in his life. I was starting to 42 being with him! We continued talking about why 43 is so beneficial both to the giver and the receiver and different ways to 44 it. As we arrived at my destination, I 45 my fare. But I pulled out an extra $20 and said, “Since we’ve been talking about this whole time, I wanted to share that 46 with you. I’ve already paid my fare, but here’s an extra little bit. You can 47 it, since you’re already down $70 from the airport. But if you want to experience the 48 of the gift, then tell the next passenger in this taxi that their ride is a gift from another and they can 49 their gratitude(感激) in whatever way.” The man turned toward me, tears in his eyes, and said, “Sir, I have a better 50 . You give that $20 to a 51 person around here and I’ll treat the next passenger with a 52 ride myself. Wow. This man was 53 10 minutes ago. I got out and walked around trying to 54 someone who needed help before heading to my destination. It was an honor meeting that driver and 55 the lesson of how everyone is capable of giving.
