The only people in real life i have met who have ever complained about small talk were in the context of "i do not care enough about [the people around me] to pay attention to anything [they] say not directly relevant to me/my hyperfocus" and i just realize they're the "everyone else is an npc" crowd and let them be sulky all the time and hate every social thing they have to do, and I'll have a fine time chatting with the cashier about her day! These are always the same people who say everyone else is boring, not that they have given anyone the time of day.

Tbh if they see others like that im happy to not give them my time and show interest in them either. All social is give and take on every level and those people are always takers. We're where we are now because of people who can't bother to care about the lives of others.
