Once upon a time there were four individuals named EVERYBODY, SOMEBODY, ANYBODY and NOBODY.
There was an important job to be done and
EVERYBODY was asked to do it.
But EVERYBODY was sure SOMEBODY would do it.
ANYBODY could have done it, but NOBODY did.
SOMEBODY got angry about it because it was EVERYBODY'S job.
EVERYBODY thought ANYBODY could do it, and NOBODY realized that EVERYBODY would not do it.
It ended up that EVERYBODY blamed SOMEBODY and NOBODY did the job that ANYBODY could have done in the first place.
