Challenge!

Now that's something you don't see every day.

Just now, a young woman passed by, walking her dog. The dog was not on a leash. Buster, as is his wont, rushed to the bedroom window to register his outrage. The other dog ran up to the other side of the window to defy him.

(I think the young woman must have called the dog back, because it returned to her after a few moments of exchanging menaces.)

That takes a certain amount of brass, I must say. Buster was absolutely furious.
