I'm quiet and generally keep to myself. I've been at my current job a few years so I've managed to make some friends who don't seem to mind that I'm awkward and quiet, but they are mostly introverts too. Everyone else is really social, having lunch together and hanging out after work in big groups. But even if I'm invited I just don't fit in and they're all too loud. Most of them look at me as a weird loner, but since I have a few mutual friends they seem to accept I'm probably just shy or boring, or both.
Most places I've worked it's been the same - I'm quiet, but since I work so hard and seem happier doing the 'boring' tasks others hate, people tend to be nice to me (especially managers, they just take advantage of it). The bad thing is no matter how hard I work I never get promotions, even though I know I can do a lot better. I'm one of the most experienced and knowledgeable on my team, yet it's always others who get pay rises. My boss has even taken credit for my work and ideas.. I tried saying something but it backfired and I ended up having a massive meltdown, which was used as an excuse not to give me more work. I just can't 'play the game' when it comes to office politics and I always come across badly, even though my work is always good. I should leave, but the job itself is perfect for an aspie (not much contact necessary with other people or customers) and my chances of getting something similar are limited
