Several years ago (about 6 now), I was remodeling my first house. It was a very modest fixer-upper (like a lot of young couples buy for their first home).
Sometimes we'd wear clothes in the house, and sometimes not. I still recall painting the bedroom in the buff.
Think of how surprised, and happy, we were to open up a wall and find two photos.
These snapshot, taken some 20 years before (and presumably not seen since), depicted another young couple, so simliar to us, doing exactly what we'd done. It was almost uncanny.
