EVERYBODY, SOMEBODY, ANYBODY AND NOBODY?

This is a story about four people named:

EVERYBODY, SOMEBODY, ANYBODY AND NOBODY?

There was an important job to be done – safely.

The equipment had to be isolated and EVERYBODY was sure that SOMEBODY would do it.

ANYBODY could have done it, but NOBODY did it.

SOMEBODY got angry about that, because it was EVERYBODY’S job.

EVERYBODY thought that SOMEBODY could do it but NOBODY realized that ANYBODY wouldn’t do it.

It ended up that EVERYBODY blamed SOMEBODY when NOBODY did what ANYBODY could have done.

What is the moral of the story?
