You remember that person in high school? The one who was picked on because they were, well, different?
We used the description “marched to the beat of a different drummer.” They did their own thing and didn’t worry about what other people thought. And, we called them “strange.” The rest of us were busy trying to make sure that we fit in with the same clothes as everyone else and that our hair was the same as everyone else. We were all afraid to really express what WE liked and what WE wanted to do.
