The closest I know is a co-worker who would say "I'm picking up my bag now, and leaving".....then she would.
Yes linkat, I've felt that, and not always during a time of stress.
Sometimes I think I could just go somewhere else, get a job where I didn't have to have a lot of responsibility, or talk to anyone. I could tell tell everyone I prefer to go by the name "knifepoint" or "peaches" and it would just be taken at face value. I could tell everyone I like to go by the name chai, or iocosa (my name in latin-kinda).
I could be invisible, and just observe the world.
