Everybody, Anybody, Somebody, Nobody

"There is an important job to be done
and Everybody expects that Somebody would do it.
Anybody could do it, but Nobody did it.
Somebody gets angry about that because it is Everybody's job.
Everybody thinks that Anybody should do it,
but Nobody realizes that Everybody would not do it.
It ends up that Everybody blames Somebody
when Nobody does what Anybody has to do."
