Yes, socks. What is it about socks? Does the washing machine eat them or something? I have this huge bag of (clean!) socks that seem to have somehow lost their mate. Every now and then I'll find one, but not before new ones have been added to the bag first. I have no idea what happens to them.
It's probably not too much of a bad thing though, as all the cats love the sock bag... as you can see above. mmmmm snuggly.
