high school graduation

High school graduation, when every body can act crazy after they are done B)
My high school graduation didn't get too crazy and I don't know about how Japanese graduation works but, every body wears a gown at my school. Girls wear white and boys where blue. And if you have high grades in a perticular class, like honors or AP or with over 100 hours of service hours you get a ribbon to wear too :D When the ceremony starts the best singer in our class sings the anthom, the class president gives a speech, a special guest speaker we hired gives a speech, then the teachers calls out our name and we get out deploma! At some high schools some times people get crazy during the speeches or name calling like bringing party crackers or something like that, mine some body just blew up a beach ball and every one was passing it around (lol)
