Friend’s pain comes and goes, especially in parking lots

DEAR ABBY: My friend “Alma” has a handicapped parking permit. I never asked her why she has it. We regularly go for long walks, and she seems perfectly able-bodied. Alma did share with me once that she got the tag after an accident left her with some intermittent long-term pain. She said most days she doesn’t need the accessible parking and doesn’t use it, but that when her pain flares up, it’s helpful to be able to utilize a handicapped parking space.
