The End of The World

Why is everything in high school a crisis?!  Every little thing that goes wrong is treated as a tragedy.  Your girlfriend/boyfriend breaks up with you?  Oh that means you should pout and just be plain nasty to everyone you come in contact with for a week, until you get to the "I hate my life" crying stage.  Don't agree with what a teacher is saying? Oh that means you should talk about how much you hate them and want them to drop dead.  Seriously, why does everyone have to be so dramatic?  Other than providing a way to get you into college, high school is not important.  Nothing that happens will be relevant to your life as an adult.  So why must we treat everything like the end of the world?
