My rug died.
Or, rather: Archie killed my rug.
It's OK, I obviously expected it; potty training has not historically been my forte with either canines or humans. Very fortunately, the particular rug that Archie killed was a simple jute rug that I didn't expect to last very long, and that had pretty much been beaten to death already. But this room really needs a rug; it just looks so ungrounded without one.
