In Person vs Online

In person, I am very quiet and unassuming. I wouldn't necessarily say I'm shy, but I'm anxious & unsure how to talk to others lol. And this commonly comes off as just seeming shy to those around me. It is always quite funny to me when people see my "online persona" or find out what I do for work, or even just start to flirt with me & have me reciprocate, because they always say they feel like I've "tricked" or "deceived" them in some way! I constantly hear "but... you look so innocent and sweet!"
