So what list are we talking about? Do I need to be worried?
I tend to mirror and copy feelings at people. I copy other people's reactions, ideas, thoughts, demeanor, ways of speaking. Mostly because if I were myself, I would simply be quiet, and not interacting with the world is dull.
I am myself when I apply those acting tools to do things I find fun, and play the game that is life. I am not myself, because this person that seems to do things, want things, experience things, is just a changing tool.
