I became interested in keys when I locked myself out of my house on a rainy day in February. I was barefoot and had no phone or coat. I had plenty of time to wax philosophical about the importance of keys as I waited in the freezing rain for someone to come home and let me in. I thought about them both symbolically and practically. I even began to see them as magical objects, talismans that allow us entry into the realms we inhabit.
