My best friend in middle school had Cystic Fibrosis. She had beautiful red hair and an incredible laugh. She laughed a lot, but she also coughed a lot. We kids got used to it, but people who didn't know would often ask her if she was sick. Jenny was tired of that question. She wanted to play, to learn, to tell jokes, to ignore the hospital visits and the treatments, to just be a kid. Our paths diverged as we got older, I moved to the east coast, and she stayed in Michigan. One day, when I was in my early twenties, I was sitting in a quintet rehearsal and I got a phone call. My friend had died. I still remember that day like it was yesterday. When a friend is gone like that, it puts a hole in the universe. I'll run in her memory, and for all the Jennys in the world and the people who love them. I'll run for them, too.
