My house is a mess. My kitchen -- the floor is dirty but the sink, counters, dishes, refrigerator -- the things that go into food prep -- are clean. I am not a clueless slob. I know what it's like to live in a clean house and I know what it takes to get and keep one that way. I just don't want to be the person who does it!
And I admit to the packrat thing. A lot of what is piled up around me is stuff I need and use, but which has no home. A couple more bookshelves and a filing cabinet or two would help, if I had a place to put them. A lot I could get rid of, but it's all mixed together with the good stuff.
My daughter "did me a favor" and cleaned up my bedroom once. Her method is to just shove everything into a trash bag and pitch it. She pitched two shoes (from two different pairs) and the original of my birth certificate, and I strongly suspect most of my CD collection (in a wallet-type holder). These days, if she puts out a bg of trash I go through it first and haul out stuff like kitchen towels, scissors, new rolls of scotch tape, etc.
