They are waiting at the bus stop

A husband and wife, accompanied by their nine children, wait at a bus stop. Shortly after, a blind man joins them. When the bus arrives, it’s overcrowded, allowing only the wife and the nine kids to board. As a result, the husband and the blind man decide to walk.

As they walk, the husband becomes irritated by the tapping sound of the blind man’s stick on the sidewalk. He suggests, “Why not put a piece of rubber at the end of your stick? That ticking sound is driving me crazy.” In response, the blind man retorts, “If you had put a rubber at the end of YOUR stick, we’d be riding the bus, so shut the hell up.”
