I sympathize. My late boyfriend had Parkinson’s. He looked hale and hearty, but it was very difficult for him to walk. He got lots of nasty looks. (Since he had the ruddy complexion, tendency to perspire and awkward gait that often go with Parkinsonism, he was sometimes taken for a drunk.) People need to be a little more tolerant — don’t assume you can judge by first appearances.
when I was on my bike, I parked legally in a HC spot in the local strip mall. It was like seven am on a sunday, so there wasn’t a whole heck of a lot of activity.
some guy went up to me threatening to call the cops and have me arrested, called me all sorts of bad names, etc. I told him to go right ahead and that either I was going downtown foro illegally parking (which I wasn’t), or HE was going downtown for Breach of PEace. I kindly offered to wait with him, but he shuffled off.
BTW: I showed him the HC plate, and he pronounced it a fake. Everybody knows that motorcycles cannnot be handicapped!
