there are a ton of reasons
first, you can go to nightschool instead and earn a degree in a profession that is really in demand and get a good job with good benefits and a pension and all the other perks
if school is not for you then you can learn a new craft, such as pottery making or knitting or sewing or anything----hell, learn Arabic so you can translate terrorist speeches for the FBI or something----anything at all!
or you could sit at home and watch a good television show in your favorite robe and bunny slippers and have a good time!
me, I should have stayed home and just do regular homework and not fall behind in school like I often did!
I could think of a million trillion reasons to not go to those stupid reasons!
