When I lived in an apartment, I had a couple of hundred books that I didn't use much stored at my mother's house. When I moved to my own house, I went through those books and put about fifty or sixty by the side of the road, with a sign hanging on a nearby shrub saying, "Free Books".
It happened that the house next door had been sold, and the old and new owners were in the process of transferring control. Apparently what happened was that the purchaser, seeing the free books, took about ten of them that he liked and temporarily stacked them on the front porch. The old owner (a hot-tempered and somewhat flaky person) came along later, saw the books, and thought they were an unwanted gift from me. She was angry at their presence, and threw them into the front yard. :-)
I later heard about this from the new owner, who was perplexed that she'd respond that way (after that incident I was glad to see the old one go). So, apparently, not everyone appreciates the presence of books.
