When I was in college my roommate and I had a goldfish. Joey was a big goldfish and had a nice big tank all to himself. He was fun to watch. He also served another purpose. My roommate and I could tell what kind of day the other had had with the answer to a simple question: Do you feel sorry for Joey today or do you wish you were him?
You see, on a good day you felt sorry for Joey because who would want to be stuck in a tank when there is so much fun to be had in the world. But on a not so good day, you wished you were Joey so all you had to worry about was swimming, and eating, and swimming some more.
What about you? Do you feel sorry for Joey today or wish you were him?
