You know this story already, or at least you should. It's a pretty simple one about getting involved. It's a story about four people: Everybody, Somebody, Anybody, and Nobody.
Now it seems 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 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.
Get the picture? Get involved. Ask some others to get involved too. Don't just assume that everybody else is going to take care of things. If we ALL pitch in, just think of the great things we can do!
