How do you address someone slightly older than you and whom you don’t know very well?
I’m wondering how someone in their say twenties would address a male acquaintance who is only a few years older than them. Like say I was in my early twenties and I had met someone that I’d only seen a few times and who I didn’t know very well. If they are older than me, isn’t it considered rude to address them with (ssi), and it would be quite odd if I called them (oppa). Would you call them (ahjussi)? I believe this word is used for men above their thirties or forties. I’m am very confused about this, I know how to address friends, family, people in the workplace, and I think acquaintances younger than me, but not acquaintances older than me, mostly by a couple years.
It is always proper to address a slightly older acquaintance by their first (given) name unless their social stature requires you recognize the difference in that stature, then it is appropriate to address them as "sir" or "ma'am."
