Rightly said! Additionally, is worth getting good at enjoying small talk as a good way to get comfortable (and help others get comfortable!) in novel situations.
The goal isn't to imagine that every exchange is an opportunity to make a friend and build a relationship, although that is true. It is to build a respect and appreciation for reading and giving social cues.

Vulnerability can be seen as a lack of control. And I really believe our generation is terrible at it. We say we want authenticity, but I think we want authenticity from people like ourselves.
Also, social media encourages a very performative style of vulnerability: "let me write at length about a small quirk," ignoring the fact that anxiety basically runs their life to such an extent that they need Twitter as a social outlet.
