This makes me feel so good to know that I am not alone out there! People are different, introvertion is finally coming to the forefront and is becoming more accepted. My mother, an extrovert, used to make me feel guilty about myself: "stop being so antisocial", "you need to come out of your shell". In the last few years, I've finally begun to accept myself for who I am. If you are happy, no matter what situation you are in, never feel inferior. The world would be so boring if everyone was the same.
As for work, I know some of my co-workers are trying to pick my brain, find out why I mostly keep to myself. They feel as though they need to solve this mystery or think I must be "hiding something". It's frustrating. I just want to be helpful, be efficient, give good patient care and then...go home!
As for the fakeness, I see the friendships between my coworkers (introverts are VERY observant) and I see how one minute they are buddy buddy and then the next they are talking smack about each other. I mean terrible, terrible things are said. It makes me feel even more reluctant to become close to people if this is how it is. I just really don't want to be involved.
My wish is for one day people become more aware of introvertion. Realize that this person is not cold, stuck up, antisocial or weird. They are just themselves.
