Just a few words about "Adieu". Although it seems, for some reason, to be used pretty liberally by people for who fench is not the first language (much more then -I've- ever heard it used by fench-speaking people, anyway, probably because Adios (in spanish) is so wildly used), Adieu is indeed pretty darn final. To better understand, Adieu is two words put together, A and Dieu, which means To and God. It basically means "I'll see you again when we stand before God."
