a parable

There once was a penguin. His name was Bert. Bert lived on an iceberg. His only friend was a Walrus named Edward. One day Bert felt the temperatures getting warmer. Edward would often swim the waters, and so Bert asked the walrus if the weather was indeed getting warmer. Edward said, “No, it is not getting warm at all!” So Bert didn’t worry about it. He kept sensing the weather getting warmer, and he continued asking Edward about it. Edward kept telling him everything was fine. Bert believed him. One day Bert noticed that the edges of the iceberg seemed smaller. Edward swam by, and Bert asked him about it: “Does my iceberg look smaller to you?” Edward denied this. Bert said, “Okay. I trust you. You wouldn’t deceive me. You are my friend. If it were shrinking, you would tell me, wouldn’t you? Because I would want to swim to another iceberg.” Edward said, “Don’t worry. Everything is fine!” So Bert believed him. Edward stopped swimming by. Bert noticed that the iceberg was indeed shrinking, so he leapt off the iceberg and began swimming for another iceberg. But he found no more icebergs. His iceberg had drifted south hundreds of miles, and he grew tired. Eventually a sea lion came by and ate him. His blood turned the water red and orcas dined on his remains.
