Assume- An ass out of you and me

This is a story about four people: Everybody, Somebody, Anybody, and Nobody.
There was this 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 that anybody could do it,
but nobody realized that everybody wouldn't do it.

It ended up that everybody blamed somebody when actually nobody asked anybody.
