Perhaps Simon is recovering a little too quickly. I caught him coming out of the barn this afternoon, after he nosed off the latch, slid the door across the ground with his nose, came into the barn, flipped the lid off of the aluminum can that holds the grain and was eating it when I showed up and he tried to smoothwalk his way out of the barn. No way, I said.  You are caught red-handed. I do not think he was abashed. But I remember a farmer/friend cautioning me to never get an animal smarter than you are.
