Dust

Today the bus I was in came to a sudden halt just after it turned the corner onto a bridge. There were no cars ahead of it. There was nothing blocking its way. A blonde woman in a navy uniform then called out – despite the fact that she was standing near the front of the bus – for the driver to open and close the back doors. It was the dust, she announced, that had forced the doors apart and jammed the system. It often happened on this bridge.
