Eccentrics still exist

In a bus on our way to a party, my girlfriend and I sat opposite an old Indonesian man. Despite the heat, he was wearing a hat and a nice suit with a flower on the lapel. He talked with us about all sorts of subjects, illustrating them with affected theatrical gestures. We enjoyed his company.
Later that week, we got on the same bus. When he spotted us, the old man showed no surprise at seeing us again. He was dressed as before, and was equally talkative. He left me wondering whether he doesn't ride this bus all day.
