The "What If Everybody Did" Therapy

I am a school psychologist in an elementary school. Recently I found a great bibliotherapy book for my little clients. It's called "What if Everybody Did?" by JoAnn Stover. On one page it shows a person tracking mud into the house and on the next page it shows the house if everyone tracked mud into it. Get the point? I thought I would try to make the point that we probably shouldn't be doing things, that if everyone did them, it would be a disaster. So we are making a "What if Everybody Did it at School" book, written and illustrated by five second and third grade boys with behavior disorders. Spencer fell right into the swing of things. He drew a picture of one kid pushing another on one page and on the next, mayhem. Brennan drew a picture of a boy bringing his dog to school on one page, and everyone bringing their dog on the next. The playground has fresh and warm looking brown piles all over it. Hey! Hold on! What is Ian drawing? He has a picture of aliens all over the playground. I asked him if Aliens are real and if everyone in the school even has an alien. He said no, they are pretend and no one really has one. I encouraged him to remain within the realm of reality. It wasn't easy for him.
With encouragement, he settled on drawing a picture of one boy throwing food and then a picture of everyone throwing food. Perfectly acceptable, within the limits of reality and actually even in line with the point I was trying to put across, that everyone throwing food would make it impossible to function in the classroom. Not too far into the process, however, it became evident that Ian was not shocked and dismayed, but delighted by the prospect of not one, but EVERYONE in the the school, pushing each other, bringing their dog, bringing their favorite alien and throwing food. The enthusiasm he displayed in completing his illustrations and the excitement on his face was deflating as I realized that the project had backfired and Ian actually thought that the school would be be a better place in all of these conditions. Back to square one.
