My daughter Camilla had today her high school "prom". In Finland this traditional event is actually literally translated to English as "The Old Ones' dance", and it is held in middle of the second year of high school end of February. This is unlike in USA, where the prom dance is held at the end of the high school. In Finland the last year students (seniors, who are called Abi's, short for Abiturients) leave school at the end of February, and therefore the second year students then become the oldest class and seniors in school, and therefore there is a good cause to celebrate this major event by performing a ballroom dance event for the parents and then for the entire school. The girls spend a great deal of effort to find a perfect dress for the event, and also boys have to dress formally. A large number of traditional dances are rehearsed and performed at the event. 

Here are pictures I took from the event.
