In the summer, I tend to listen to music more often than during the rest of the year. During my formative years, I was a fan of the rock group Pink Floyd, and yes, I still enjoy their music today. One of their more famous songs, “Another Brick in the Wall,” was released in 1979, the same year I started teaching, so it has special meaning to me. I made a pact with myself that I would never be just another brick in the wall, and I’d like to think that over my 32-year teaching career, I’ve made a difference.
