Bill... Do you mean to say that some Finns will say something that sounds like 'hi hi' when they are saying goodbye?
Wei... Now I have to ask you "What does 'I'm Audi 5000' mean'"? I have never heard that used as a way of saying bye bye.
Wanda... "take care", how could I have missed that one. It is so common here in Canada and as you said, very common in the US. Another good addition to the list, thank you.
SHL... sorry the word "chow" bothered you. I'll add 'howdy' to the list
Dya... that was an interesting observation
Diana... thank you for those interesting comparisons
NealC... Paul's song title also crossed my mind while I was composing the list
Wanda... I am best aware of the way native speakers speak and less sure of what expressions others use.
