We took the bus from the suburb every early morning that summer 3 years ago. One of the passengers was a small   36  man who took the bus to the centre for senior citizens every morning. He walked with a stoop (佝偻) and a sad look on his face when he, with some difficulty,   37  the bus and sat down alone behind the driver. No one ever paid very much attention to him.
　　Then one   38   morning he said good morning to the driver and smiled before he sat down. The driver 39  guardedly. The rest of us were silent. The next day, the old man boarded the bus energetically,   40  and said in a loud voice: “And a very good morning to you all!” Some of us looked up, amazed, and murmured “Good morning,”  41  . The following weeks we were more alert (留意的). Our friend was now dressed in a nice old suit and a wide out-of-date   42 . The thin hair had been carefully combed. He said good morning to us every day and we  43  began to nod and talk to each other.
　　One morning he had a bunch of wild flowers in his hand. The driver   44  smilingly and asked:“Have you got yourself a girlfriend, Charlie?”and he nodded shyly and said yes. The other passengers   45  and clapped at him. Charlie bowed and waved the   46  before he sat down on his seat. Every morning after that Charlie always brought a flower. Some of the   47  passengers began bringing him flowers for his bouquet(花束).
The summer went by, and    48   was closing in, when one morning Charlie wasn't waiting at his usual    49 . When he wasn't there the next day and the day after that, we started wondering if he was sick or —   50  — on holiday somewhere.
One day, we learned from the staff working in the centre for senior citizens that the elderly   51  was fine, but he hadn't been coming to the   52   that week. One of his very close friends had died at the weekend. They   53  him back on Monday. How silent we were the rest of the way to work.
　　The next   54   Charlie was waiting at the stop, stooping a bit more, a little bit more grey, and without a tie. He seemed to have shrinked（缩小）again. Inside the bus was a  55 . All of us sat with our eyes filled with tears and a bunch of wild flowers in our hands.
