Who?

This is a story about four people:

Everybody, Somebody, Anybody, and Nobody.

There was an important job to be done
and Everybody was asked to do it.

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 Anybody could do it;
but, Nobody realized that Everybody wouldn’t do it.

It ended up that Everybody blamed Somebody,
when Nobody did what Anybody could have done!
