Every morning after that Charlie always brought a flower. Some of the regular passengers began bringing him flowers for his bouquet, gently nudged him and said shyly: "Here." Everyone smiled. The men started to jest about it, talk to each other, and share the newspaper.

The summer went by, and autumn was closing in, when one morning Charlie wasn't waiting at his usual stop. When he wasn't there the next day and the day after that, we started wondering if he was sick or -- hopefully -- on holiday somewhere.

When we came nearer to the centre for senior citizens, one of the passengers asked the driver to wait. We all held our breaths when she went to the door.

Yes, the staff said, they knew who we were talking about. The elderly gentleman was fine, but he hadn't been coming to the centre that week. One of his very close friends had died at the weekend. They expected him back on Monday. How silent we were the rest of the way to work.

The next Monday Charlie was waiting at the stop, stooping a bit more, a little bit more grey, and without a tie. He seemed to have shrinked again. Inside the bus was a silence akin to that in a church. Even though no one had talked about it, all those of us, who he had made such an impression on that summer, sat with our eyes filled with tears and a bunch of wild flowers in our hands.
