I heard a story with a meaning about a year ago. It goes like this:
A man started walking home from work and walked by a bunch of houses, each seeming to have a dog. As he walked by each dog would bark at him, except for one dog. One house had a dog that just whimpered and moans all the time, the kind of sound like it was in pain from something. He dismissed it and continued walking. The next day the same thing - all the dogs barked at him except this one dog who whimpered, howled and moaned. This continued for a week. Finally the man became very concerned and knocked on the door of the whimpering dog to find out what was wrong. He asked the man who answered, "What's wrong with your dog?".
