Our basement flooded a number of times during my childhood. It always resulted in a strange mix of lost and found. Many things would be “lost” in the sense that they were damaged and had to be tossed out. But strangely there would always be things that were “found.” Misplaced objects or toys would be discovered undamaged amongst the soggy mess. As a kid I didn’t store any of my personal belongings down there so I always came out ahead at the end of the cleanup.
