What do you treasure that nobody else would look at twice? I have a black plastic shift key from an old electric Dog Bed typewriter on the bookcase above my computer at home. Im staring at it as I write. To you it would look like nothing except a piece of junk, but to me it means a great deal. Ive had it since 1982, from the days when I was living in a ground-floor apartment at the back of an old, squat brick building in New Yorks Lower East Side. I was renting a studio apartment, which is real estate for one room. It was 423 square feet with a bathroom so small even women stood up to pee and a kitchen consisting of an Easy-Bake Oven. The only thing of value I owned was a used electric typewriter. One night, I returned to discover that my place, usually overheated, was strikingly cold. I figured the heat was off in the building that occasionally happened but then I realized that my one window was smashed.
