That's what normies don't get about introverts: we're not above small talk, we're above small talk when it's all there is. Of course we'll ask the loved one how their day has been, and the fact is we'll actually shut the fuck up and listen to it all, and when things become serious we'll talk to say meaningful things.

Else, there's folie à deux echolalia, shitty jokes, movie lines, comfortable silence, or skipping it all to 'scorching hot sex'.
