I had gotten the impression that it was a room full of relatives, at holiday get togethers.
Question for you, when they ask; "So what is you do, in computers,...uncle...?"
That is it exactly – except my nephews and nieces do know it much better than their parents!
Up north, when visiting my mom, there are a lot of folks who knew me as a kid, and want to know what I do. I'm deliberately vague with them, because I know they're not interested in the details, only whether I'm happy doing what I do and so on, so I tend to just say "computer stuff" or "I solve all kinds of computer-related problems except those involving Windows", and maybe tell about a funny project/experience that the asker can relate to, and can counter-ask the same thing. (Except I'm genuinely curious; I could easily do nothing but ask people about their work and worldview and approaches to problem-solving.)
The more detailed discussions typically emerge because either someone has done something related to computers and my family/friends/acquintances say I'm "in the same line of work", or because they need something fixed or implemented or have some other related problem. They
ask; I do
not volunteer it.
It is
not like I inject my background or know-how into discussions! I'm much more interested in other peoples' experiences and viewpoints, and prefer to talk about that stuff –– I'm always keen to understand how others see and understand things and problems, and how they approach solving them. It is only when they do start asking that it ends up taking too long for me to explain, especially since I do not have a single focus or job title or other label that could describe what I do.
So, you could say that I'm looking for a more efficient way to satisfy non-technical askers wanting to know what I do and know about; with the focus on avoiding misunderstanding rather than to impress them.
You seem motivated by your need to impress people.
I needed to think hard about that, and I must say, I truly believe it is not the case. The reason is, I would not be bothered at all if they didn't ask. What does bother me, is that they seem to mis-assume a lot; to get things wrong –– especially second-hand from my family and friends.
I said it before: I
do need validation from other technical people, and perhaps it is something I need to work on. But it definitely does not extend to non-technical people, and even less to "people" in general.
In general, rather than "impressive", I'd rather prefer to be "interesting"; that applies to the kind of
exposition about my technical aspects I'm trying to achieve, and am asking about here.
In particular, I often mention when discussions veer that way that I personally don't know anything about Windows anymore; my Windows know-how is well over a decade out of date! I have zero need to describe my actual technical know-how, I just want them to know that regardless of what they might have heard, that facet of computing I'm completely dummy at.
I repeat: NOBODY CARES. You are tackling the wrong problem.
Quite possible. Although I'm not
convinced of this yet, I'll consider it thoroughly.
Sorry for the bluntness, but it seems appropriate.
It is, and I do appreciate it. Thoroughly honest bluntness is

in my book. Yes, it stings, but it's like disinfectant: no harm done, quite the opposite.
