A couple of years ago, I made a trip to my hometown of Cleveland, Ohio. Tours of the old neighborhood are automatically part of my visits. My cousin Arlene wanted to tag along, so I picked her up one afternoon, and off we went for our nostalgia trip.

When Arlene was growing up, she lived with her family in the upstairs suite of a duplex on Galewood Drive, and our grandparents lived in the downstairs flat. We were taking photos of the house when someone came to the front door — and before we knew it, we were inside, giggling about the pocket doors in the master bedroom and the pushbutton light switches in the kitchen, and how the place hadn't changed.
