Dear Prudence,

When behind the wheel of a car, I would never consider parking in a spot designated for a fellow driver with disabilities, as I don't belong to this group. However, when shopping or recreating and in need of a public restroom, I always opt for the bathroom stall designed for my fellow citizens with disabilities. (They are uniformly more spacious, better stocked, and I like the handrails.) I have yet to emerge from such a spot to find someone more deserving of such amenities cooling their heels (so to speak), and since my caffeine intake is too high, these pit stops are more or less regular events. Am I being callous and insensitive, or appropriately opportunistic?

Dear Doubt,

Funny you should bring this up. Prudie does exactly the same thing, preferring, as you do, the larger space, along with the private mirror and sink. Like you, Prudie has never seen a disabled person waiting, though that would not be the end of the world. Considering the length of time one may park vs. the time needed in the restroom, the issues are clearly different. Prudie often sees women take the handicapped stall simply because it becomes available first. (Prudie is hardly ever in the men's room ... unless, of course, it is an individual bathroom, and the girls' room is taken.)

--Prudie, practically

Dear Prudie,

I am surrounded by exercise nuts, both in my family and at work. Almost everybody I know is either coming from or going to the gym. I am a size 10, feel fit, and make it my business to walk wherever I can--sometimes skipping the elevator or the escalator.

Could it be that I should be engaging in a more formal kind of exercise? My health is good, by the by.
