@janneke Honestly, if you asked people that are good at and like small talk why they do it, most of them aren't going to explain it like this post does, because it's probably not something they ever really thought about
And, I would say school *is* the place where a lot of this is learned; not formally or with lessons, but just as part of socialization and (hopefully) with teachers or other leadership that take an active interest in helping kids get along
Doesn't always work, of course, but...
