we have school party's once a year for the entire school, and once again once a year for the studying year. i stopped going about two years ago. the music is so loud you can only talk in sign language or by shouting in someones ear like a boot camp sarge. and it is so loud it makes my head hurt, littereally. and they only play the worst pop, and then distort it by turning the extreme bass and extreme trebble up, but leaving the melody, as far as there is one, out.
as for booze, i'm in the first year where they would even have alcohol there, and generally, i have no need to be near about a 100 or more rich kids getting near alcohol without parents near, some for the first time.
