I have had so many folk shove by me, on lifts, narrow pavements,, etc . Now I a walking stick. I don't use it to walk. Cos I'd end up falling over it. It's more a visual aid to everyone that I'm unsteady,freeze, stumble sometimes with a festernating gait, I'm liable to run into them.
The other thing is people's sympathy is short lived. I had persistent hiccups, for a week. In the queue at my local greggs, a builder was in front of me. 1st hiccup-went unnoticed, 2nd hiccup-turned and smiled, 3rd hiccup-ignored, 4th hiccup-turned and glared. It was a good job he was next to get served, or I'd be on the receiving end of a punch.
