I love the pleased expression on the little dog's face. Quite unaware that she has done anything wrong. How could you get angry really? Or rather, how could you STAY angry for long?
This photo reminds me of the time I fed a bit of raw chicken liver to my Whitey, my cat. (Yes, yes, I know.Big mistake in hindsight, but he was nearly taking me down for it.) Right afterwards, he looked like some kind feline zombie after a feast.
