We don't have proms here in Europe
Not quite true.
There is a tradition in high schools of Finland to have a so called "The dances of the old", when the third year students leave the school to prepare for matriculation examination and the second year high school students become "the eldest" of the school. They usually include old dances but can also include some newer stuff...
Would you like to know more?They aren't a prom in the same sense as the prom in US are; they are usually more formal in the scheduled part of the event. The dances are usually performed in the school indoor sports hall (which usually also serves as the place for all other events too) to a crowd of parents, and also to younger students of the school. Also, there's usually heavy partying (read: boozing up in a real Fenno-Ugrian way) in the evening at some other location than the school.
I liked the dancing part in fact... The fact that I happened to have one of the prettiest and nicest girls in the school as my partner might have had an effect in that. But since I've never been into pouring my brains out of my ears, the partying in the evening was kinda boring, with occasional amusement from observing bursts of drunken behaviour.
So no, there ain't "Proms" in Europe, but at least here in Finland we've got something else that serves kinda same function.
