I've never been prone to feeling awkward. Nor even really embarrassed. I mean I can tell when I should be awkward or embarrassed, but I've just never really been one to care how others perceived me in any given social situation. I was this way even as a small child. I had things I liked and disliked, and I was never shy in expressing this. My teachers when I was a small kid initially thought I had some kind of "supernatural aura" because I could literally "divide a room". Meaning, I had one half of the room loving me like a celebrity practically, and the other spitting on the floor as I walked by. Hence why I have great friends and great enemies, and nothing in between. People either really like me, or really hate me. I do mean this in person btw, not online. I'm sure that doesn't say particularly great things about me as a person, but at least I'm almost always sure where I stand with the people around me, relationship-wise.
Though since I don't particularly spend much time socializing anymore, due to my own growing dislike of pretty much anyone except for my thankfully small friend circle, (I have little contact with any of my family, not even my siblings), I suppose a lot of this is irrelevant in my day to day situation. Especially work.
People say they wish they didn't care what others thought, but I have to say, its not as "free" as it sounds. It's best to try and be somewhat conscious of others' opinions about you. I'm not saying act and respond to them, but be wary and pay attention even if you don't actually change anything about yourself to fit them.
