I am perfectly able-bodied; my mom — not so much, so she has a placard that I use when I take her places.
Recently when I took my mom to have her blood drawn, I waited in the car for her, and a random dude felt it was his patriotic duty to comment on me being parked in a handicapped spot. He gets points for not taking directly to me, but instead just throwing some loud shade, but I was flabbergasted that thought I was just there parked in a handicapped space looking my phone, because — of course — I’ve got nothing better to do with my time.
There are so many things that genuinely need our car and concern, it is astonishing to me where so many people put there time.
Bottom line: I never assume I know why someone is in a handicapped spot.
