I don’t know what it is about an old key, but I do love them so. To me they represent many things….. a secret, another life, unlocking a mystery, an untold story, a surprise, sentimental value, or maybe even sadness to some degree. My grandparents had these keys to a couple of bedrooms in their house. They never locked the doors, so the keys would just be left in the keyhole sitting there…. but it was definitely great for a kid with my imagination.
