Have you ever accidently frowned when meeting someone?

Not that I can recall, but it’s hard to see my own face.

I can carry an expression, that can make people think I’m not very approachable.

I think I look, and am friendlier, than when I used to drink.
I worked as security in SO many different places. It was easier work, if I appeared very stern.

I try to think about my body language, always. Some people, will get a confused or stupid look on their face, when I’m talking to them. I always wondered, can they tell they look like that?
