A friend of mine visited my new flat and was in my room for the first time. Not familiar with the internet.
a trenchant unfamiliarity an aversion to knowing about it. an aversion to unfamiliarity; call it technophobia.
That kind of aversion is very tricky. I wouldn't try to show anything, for fear of complicating his worries about the complexity, which might complicate his worries about the difficulty.
I show him something he doesn't understand, doesn't relate to, or which doesn't interest him.... then it becomes more daunting for him, and more tedious.
