Outside the rehab hospital, if I bump into another stroke patient I know, I say hello. Naturally. Trickier etiquette is how to comport yourself when you see a stroke stranger. I have an urge to run up to them: “I'm with you!” “I know your pain!” “Keep fighting!” which I squelch.
I once sat across from a stroke stranger on the Boston T (subway). He was older, had a cane as well as the hand that didn't work. I could tell that he had noticed me. Suddenly, at the top of his lungs he yelled, “She has the same problem that I have!”
Passengers in the car turned to look at him, and then at me, curiously. Oh dear. I made a beatific smiled, but remained silent.
More unlucky than I.
