I've figured out the some people see potential in many things that others regard as waste. As a result their place usually is a mess. I'm not sure at what point it becomes a real problem, but I know it certainly can turn into a trap of its own.
People who have no mechanical aptitude or are well off financially typically have neat places.....in the first instance, it's because they can't put two parts together, and in the second case, they don't need to.

Druggers and Drunks are not part of this scenario. They are like tornados....going through life tearing the crap out of everything they touch and leaving others to pick up the mess.
