You make a fair point. Perhaps it’s just the cultures I’ve lived in, though, but my impression is that the vast majority of people value some amount of what might be considered small talk. So for those of us who don’t take to it naturally (and I am also one who’s had to learn small talk… I’m okay at it in many situations now but not all) it’s probably worth having a feel for it for the sake of friendly relationships with many people around us.
