i guess one contributing factor to me having (had) such a hard time with grasping plurality is having only been exposed to it "third-hand"; in other words i just haven't really had any personal connections with a plural person, or even talked about it with... one?
like i kinda feel like my initial exposure to it was pretty much just seeing people go
"hey uh, i guess i'm plural. this feels a bit weird but i'm gonna roll with it"
then i never did any digging myself, and at some point it was just Normal - to them, but not for me. and now that i've found that, Actually, I Might Also Relate to this experience in some way... i just feel anxious, and alone.
