Mirroring does tend to encourage others to think you are just like them... I notice a lot of politicians, sales ppl and religious professionals do this.

I use to practice the emotions of others in a real mirror, so I would properly respond with the correct emotion when I was much younger. I got in trouble & mocked for not displaying the right affect or emotion. Now I am able to do this with my own gear, but it was hell from ages 5-25-ish
