I'm always confused when people on campus don't have earbuds or headphones. I have to wonder how they get by walking by themselves without some sort of musical background.
Then again, people who aren't heavily into music confuse the hell out of me. It's as if they're simply ignoring a fundamental part of the human mind. I could be biased on this because I have some musical talent. Nonetheless, music is a core feature of human culture. How can you ignore that?
