Godfather Death

Unlike other tales we have read this week, Godfather Death does not include any type of detail about the young boy. In this story, the father was simply a poor man and needed a godfather for his thirteenth child. After a careful selection process, he chooses Death as the right match for the job. After we learn this, the tale is absent of the boy's growth into manhood. Instead, we are just told that "when the boy was old enough, his gosfather appeared one day and told him to come along with him." Does this mean that Death had not seen his godson until now? Where is his mother? How have things faired for the boy? We don't know and these things simply remain as mysteries. The boy becomes a famous doctor and as readers we are left out of any information that would give us a sense of whether he is ready for such a title or not. Clearly, however, he is not because he disobeys Godfather Death and has to pay the price with his life. In other tales, like "Clever Hans" or "The Wild Man" we see the boy grow into a man, and in the end he lives happily ever after. What are we then to make of the omission of the doctor's boyhood and the ending of this particular fairytale? Do they have some sort of correlation?
