Years ago... For a summer job, I read residential gas meters. In newer neighbourhoods, the meters were on the outside. But in many cases, I had to enter the older homes. I was in several houses of hoarders and I've never been more frightened when I had to shimmy through tiny walks ways built of newspapers, boxes and stuff/junk piled to the rafters and make my way to the dungeons(basements). Houses that stunk, with dog or cat excrement and urine. One guy had saved all these massive empty dog food bags. I have no idea where these people sleep, never mind cook or sit down. Madness.
Those experiences keep me from hoarding anything, although I do have a shoe fetish...
