We're moving in two weeks, and we've begun the purge of books and CDs that we no longer use (to be donated to the Friends of the Library sale) and clothes that we no longer wear (Goodwill all the way). This can result in the occasional "what the hell?" moment when we realize that not only can we not remember when we got a book or CD, but we can't remember *why* we got it in the first place. Sometimes the answer is "for curiosity's sake," as when I found myself calling down the stairs to my husband, saying "Honey, do we need to keep 'Cavies for Fun and Profit'?"
[N.B. "cavy" is a specialist term for "guinea pig."]
