I was so stunned when I left college and realized how much I have to limit my vocabulary around most people. It made me feel distant from many of my peers.
To be fair, there are a lot of things that you learn in college that are supposed to be specialized for your field of study.
I was told that I was being condescending when I use words that nobody else understands. To put it in the words of one boss: @inetknght, you're smart and you do good work. But, @inetknght, you can't handle stupid. So I have to move you to another team.
It was kind've eye-opening to realize that stupid people don't just exist. They're all around us. Always have been. Being moved to my own team of one just so people wouldn't feel dumb around me definitely made me feel distant too.
