thinking about (a particular sort of) "social unawareness". i feel like, some of the time it's something that can be remedied by being more considerate and thoughtful of others in conversation, and other times, the 'socially unaware' person is a lot more aware of it than others realize. and in those cases it's more of a situation of the person having certain social needs that their surroundings are not accommodating.
for example, things like me always having a need to infodump about minecraft or tf2 or whatever when i was younger, and later having a need to talk about math. i think it may have seemed to others like i was centering my own needs and interests when i was doing these things, because i wasnt in a space that was conducive to them.
in the end, i did eventually wind up seeking and creating the spaces that would allow me to talk about the things i want on my own terms, and generally engage in the kinds of activities i enjoy with people who would enjoy them with me, and in these spaces and contexts i am positioned as 'socially aware'.
im sure in some ways i learned to be more considerate of others, im definitely more conscientious of boundaries and stuff now than i was 5 years ago. but just plain not having a need met or a space not being appropriate/accommodating for a need (it of course depends on context whether the space should be expected to fill the given need) also contributes substantially to a person being perceived as 'socially unaware'.
