>>2070This is actually a thing. It's basically your subconscious affecting your body language, posture, and facial expressions.
I've managed to do it consciously. I can give people a 'fuck off I'm busy' vibe to ward them away, or be open and welcoming and helpful.
I don't really like doing it; it feels dishonest and like I'm pretending to be someone else.
Probably because I AM pretending to be someone else.
