FFF: Things You Should Know

I do not understand this story at all.  I am so confused as to what the list really is.  This little boy missed a day of school when his teacher handed out a sheet of "Things to Know".  It seems like this sheet of paper, if it even really exists, has manipulated everyone's mind, or this little boy is just crazy.  Why did he have to go to a psychiatrist?  Also, how did so many people get this "list" if the teacher just passed it out in her classroom.  I do not like this story because it makes absolutely no sense.
