A pizza box spotted with grease here, a crumpled old newspaper there, a bag of assorted trash tossed in an empty corner. One discard followed by another is such a slow buildup that it goes unnoticed. It's similar to gaining weight. A pound here and a pound there isn't noticed since it is just a gradual increase. But, link days into weeks, weeks into months, months into years and years into decades, and the accumulation becomes staggering. The first pizza box morphed into mountains and the conditions surpassed hoarding, it was a super-hoarder's house.
