What?! SELL my books?! NEVER! I will keep them till they collapse the house! HaHa indeed!
However, in the interests of not collapsing the house, I have sworn off buying any more books. Not one new book. For the past decade, I have resisted even the temptation of library discard sales, and stuck to taking books out on my library card, and returning them when done, thus keeping the book infestation from growing any larger - though admittedly doing nothing to shrink the collection already in place.
