Everybody is Nobody

This is the story of four boys named; everybody, somebody, anybody, and nobody.
There was an important job to be done and everybody was sure that somebody would do it. Anybody could have done it, but nobody knew that everybody would leave it for somebody to do. Somebody got angry about that because it was everybody's job. Everybody thought anybody could do it, but nobody realized that somebody wouldn't do it. It ended up that everybody blamed somebody when nobody did what anybody could have done.
