For friends and family? Yes.
For acquaintances, people just above the level of stranger, I don’t see how.
For instance, I work with a guy who occassionally reeks of urine. Not body odor, just urine. Sometimes he doesn’t smell like urine at all. So I assume that he has some chronic condition, maybe involving a catheter or an adult diaper or something.
As much as the smell of urine repulses me, it does not keep me from interacting with him (which isn’t very often, but every so often we have to talk about work-related matters). I would never ask him, “Hey, why do you sometimes smell like urine?” Not only because it would point out his differentness and probably embarrass him, but because I might be uncomfortable with the answer. “See, I was having rough sex one night…”
It’s also none of my business. If we were friends, though, I would feel more comfortable. Though I would probably wait for him to broach the topic first.
As someone who often sticks out (black woman in a field dominanted by white males…a bit eccentric…movement disorder), I have a number of topics people could ask me about. Occassionally some person will ask me about a “black people thing”, but usually this person is someone who I have had deeper conversations with besides, “Hey, the weather is nice today!” I do not take offense by co-workers’ silence or take that silence to mean that people have misconceptions about me as a general rule, although a few most certainly do. I just don’t think I’m interesting enough for folks to be studying me like that. And as I said before, everyone is a mystery to everyone else (or at least they’re a mystery to me!) I don’t know what it’s like to be a white guy in a wheelchair (assuming you’re white) anymore than you don’t know what it’s like to be a black woman who lives a rather unconventional life. I think we could all start a “Ask a person” thread and learn something new.
If the two of us worked together, would you be just as curious about me as you think you’d expect me to be curious about you? If so, how far would you take this curiosity? I know this kinda sounds like a snarky question, but it’s honestly not meant to be one.
