@engineer,
It depends, usually these are people who act like they have something to hide and then when they first look at me they act very paranoid around me although they don't even know me. I have had encounters with a group of folks who act like they are up to no good (whether at work, at a party, wherever) but for whatever reason I am the one they usually mistrust or are afraid of and believe I have something up my sleeve ðŸ¤
