three day weekend

So what is the difference between a two day weekend and a three day weekend besides an extra day. I mean what makes people including me look forward to a weekend with an extra day is it really the extra day or is it the shorter week that follows. Could it be something else? Could it be that I'm tricked into thinking that the extra day will hold untold wonders that if I went to school would not have been? Could it be just that I hate school so much that even two seconds away from school would be enough to get me excited beyond all comprehension? I'm not sure though I have a pretty good idea.
