Hit and wheel away

Another good moment from the wheelchair clinic: "What did you run into?" asked the therapist.

Everything, I laughed, and the wheelchair salesman, who uses a chair, laughed with me.

No, said the therapist, I mean here. She pointed at the left front of my chair.

Your caster is all bent and your fender is broken, she added.

I reiterate now: I run into everything, often with my left front.
