I save tickets like this and put them in drawers. To have tangible memories of moments. This is from the subway in Berlin. Such things are becoming obsolete. The new style of receipt fades into invisibility now after only a few years. A glance at this is like smelling a flower. I get an essence of that experience. I see flashes of the train platform. The Roma family gathering around us as we bought tickets. The smooth quiet ride. The history baked into every building and sidewalk. It's all there in that little rectangle if I look hard enough.
