I vibrate wariness at the approach of strangers, and have a face within my Janus repertoire that is labeled: "off-putting." An approaching stranger, having passed by those cues, will -- at some point -- realize something is off, as if I'm holding my breath 'til the conversation's end - but not that, precisely At any rate, they will yield to whatever it is, in due time. [Maybe, I seem contagiously itchy.] Remarkably, I went decades without realizing any of this. To be fair, I never get a good look at myself at the moment I'm meeting a stranger. [And, if I did, I wouldn't have the brainpan bandwidth to do anything with the information.] Now, I'm training myself to behave elsewise, but the score is still 50 years to 1.
