The person I present online is pretty much the one in real life other than I come across as aloof at times in real life. I am not a social butterfly, am shy, can “lay on the charm” when needed, but, really, prefer to be rather quiet and have a small social circle.
This results in an occasional appearance of aloofness and disdainfulness. I am painfully polite and courteous to strangers rather than friendly as I am online.
If I am comfortable, such as at a biker party or in a martial arts Dojo, my comfort shows in joking, comfort, and just fitting in, but the aloofness is very prominent other than my comfort areas. I am also at ease with some of my co workers and generally at ease when working with my patients.
I am less likely to get into controversial debates in real life because it is much easier to click the “off” button than it is to walk away IRL.
