I only have the basic reception cable, so I don't get A&E. I'd be interested in watching it, though I saw a program (maybe Oprah?) once about a woman who hoarded and it sickened me.
I knew a woman once who hoarded. She was one of those people you think are totally together, someone you'd choose to lean on in a pinch - but she had this other side. In her case, it's partly about loneliness. She has a boyfriend and a thousand friends, but no real family. She and the boyfriend have been together for decades, but they're never going to live together because he likes things clutter-free.
