I have learned a new twist to this story.
Apparently, the entire condo complex I live in is aware that my brother moved out during COVID and I took over his place.
I do not have a brother.
I was just a shut-in, especially during COVID, and didn't really start coming out until I had transitioned.
Still intermittently giggling about the time a neighbor asked me how my "brother" was doing and had to reply with, "Oh, he's doing great these days!"
