How's my driving?

The bumpy ride into town threatened to put my spine out of place. The bus stopped abruptly and I lost my grip on the handrail and, consequentially, my footing. Twisting sideways, the comic scene culminated in an uncontrollable lurch backwards, and I landed squarely on the lap of the middle-aged lady sitting in the disabled seat. What followed must have been a delayed reflex action, because my arms shot backwards to cushion the fall and I elbowed her in the face. She started crying. I asked whether she was hurt and apologised profusely. She ignored me and kept on crying. I asked again, by which time some of the other passengers began tittering. There was no blood and no response, just a telenovela-style sobbing. I was mortified by my clumsiness.
