Once upon a time there were four people named Everybody, Somebody, Nobody and Anybody.- Author unknown
When there was an important job to be done, Everybody was sure Somebody would do it.
Anybody could have done it, but Nobody did.
When Nobody did it, Everybody got angry because it was Somebody's job.
Everybody thought Anybody could do it, but Somebody realized that Nobody would do it.
So it ended up that Everybody blamed Somebody that Nobody did what Anybody could have done in the first place.
