That was such a good letter! So true. When I was younger and Irv was not in a wheelchair I had a few years when people would criticize me for parking in the disabled zone. I would only park there when there was no room near the entrance I was aiming for, because I could walk, although I would sometimes get too tired and stagger or meander. When my husband ended up in a wheelchair, of course, we had the permanent wheelchair lift on the back of the car, and no one barked at us any more. The disabled pass was mine, not Irv's, he didn't take the time and effort to get one since I already had one, and I did the driving by then.
The big problem for which I needed the parking space was not total inability to walk...it was that I sometimes got tired easily and began to walk "funny", although still walking.

I miss my husband whom I put in and out of the car and into his wheelchair. He was the light of my life.
