I installed internet into people houses for fifteen years. My sample is pretty broad. It is far nastier than most people realize. There majority is decent but it would be close to one in ten is very nasty then another one in ten that will have nice common 'public guest ’ areas but when their basement and different story. It is really hard to tell from the outside and often the people seem normal. Hording is really common but then you get hording wet garbage as well.
