For a big chunk of my adult life…all of my 20’s, half of my 30’s…I put a huge amount of effort into avoiding people. I socially isolated, worked a graveyard shift. I was good at this. Disappearing, I learned, is my one real talent.
The exception to this habit: every few years I would visit with my family at Christmas. Everyone would get together, do the traditional gift/meal/football-watching thing.
