This is a really vast topic.
I’ll try to summarize some salient points.
Social interactions, camaraderie, and group eros, are mostly about energetic tuning. Everyone tunes into a similar energy space/context.
The words and activities then exchanged, are all a play, happening within the common context.
If you can harmonize, tune in, to the other’s/group’s energy signature, then you can say whatever you want, and it will be globally accepted.
On the other hand, if your energy signature does not tune into the other’s/group’s energy, then your very presence itself will feel awkward, even if you choose to say nothing.
So the essence of social interaction is = “energy/context tuning/harmonization”.
It is a certain trance, a certain absorption.
You bridge the distance between: Where you are, and where the other is.
There are different combinations possible:
# You go all the way to them [Codependent]
# They come all the way to you [Narcissist]
# You go all the way to them and then they come all the way to you [My preference].
# Both meet somewhere in the middle [Common dissociation, The general social reality and formal situations fall here].
So essentially all interaction/communion = is about bridging the distance, and closing the gap.
So really, the capacity you have for communion in social interactions depends on your conditioning/investment/interest or desire.
If you are relatively de-conditioned, then you have to make the stretch to meet the conditioned others. Often they cannot come to you. You go to them.
Situational friendships are because both the people are tuned to a common context, which is like the 4th combination in my list.
These friendships fade, when the common context is vacated.
A person permanently in the societal frame, has substantially repressed his individuality, and entirely invested in the middle ground. He enjoys communion at all times, but at the cost of his deeper individuality.
On the other hand, a hermit might happen when his conditioning is such that meeting others is too much of a stretch. So he lives in his own space/authenticity, until the other comes to him.
