This Thing

This thing has been roaming around our house ever since we got married.  I don't know what it is or why we have it.  Whenever it is found again Ryan says, "Oh, Salli wrote though, not Andy."  Then he suggests that we take a picture of it.  We've taken quite a few pictures of it, I think.  Then it usually disappears until it is found again, although, I know exactly where it is right now.  (Sitting awkwardly on the stairs because it's not mine and I don't know what to do with it.)
