A
A few months ago I was at a bus stop in town in the evening. The bus came on time and I took the window seat. The bus route was by the seashore and I was enjoying the breeze （微风) while watching the sea waves. After a few minutes the bus made its next stop. A young boy and a girl got on. They were standing on my left when the bus pulled off. I looked at them curiously and realized that all the window seats were occupied （占据). They could sit but not together. Suddenly a different wave passed through my body and my inner mind gave me the advice to get up. I got up and offered them my seat. The young lady smiled kindly and said thanks. I occupied another seat and we parted our ways. I don’t remember whether I got off the bus before them or not.
Months passed by. Suddenly one day while I was standing at the same bus stop waiting some time for the bus to arrive I heard a voice.
“Excuse me, Uncle.” I looked in the direction of the voice. It was a beautiful young lady.
Puzzled, I said, “I do not know you.”
She said, “Do you remember you gave us your window seat？”
Puzzled, I said, “Maybe, but what is so great in that？”
She said, “If you had not given your seat that day, perhaps I would have not sat with my friend. By sitting together it helped us bridge a misunderstanding that had been between us forever. Do you know we are getting married next month？”
“Good! God bless both of you,” I replied.
The young lady again said thank you and went on her journey. I realized the importance of giving that day.
Why were the young boy and the girl standing on the bus？A. Because they wanted to enjoy the sea view.
B. Because they preferred to stand.
C. Because there were no empty seats.
D. Because they couldn’t sit together.
