Knock Knock. Who's There? Pinot!!!!

Sometimes I think the Old Guy is losing it. Today, while he was home making lunch for himself he thought he heard someone knocking on the door. He raced down the stairs, opened the door and no one was there. Then he turned around and realized what he was hearing was Pinot doing a major dig in the kitty litter that sounded just like someone knocking at the door. If you ask me, I think the Old Guy needs professional help.
