I have encountered this too , many times. But now that I am older, I am finding there are other types, you just need to find them as friends. As far as coworkers go, you can't really avoid them, and if you try to be different, they may single you out and make things difficult for you. I am not sure what to do because you really can't change people. Maybe find someone you notice not doing it, and try to hang out with them. Good luck. You are in a tough situation.
