When I was a boy, we had a Saint Bernard. Like all Saint Bernards, Charlie was a big, slobbery dork of a dog. Charlie was a good dog. We also had several cats, one of which was named Batman. (We named all of our cats after comic book characters.)
Charlie and Batman were best friends. Everywhere Charlie went, Batman went too. At night — especially on cold winter nights — Batman would climb onto Charlie’s side and curl up in his thick fur. They’d sleep contentedly for hours, best buds.
