I was in the park the other day with my dog Rufus, throwing sticks and whatnot.
He was just as happy as a dog can be so I asked him.
"Rufus! What is it you like so much about sticks?"
He turned around a looked at me straight in the eye like he could not understand that I didn't know already; that it was so obvious that there was maybe not even any explanation.
But then, just before he started to play again, he said, “Bark”!
