"Well Met" - What! It's combat?

[neloon]

As tripleblessed implies, "well met" is just a usage that has become obsolete in the UK although, even in Shakespeare's day, it would not have been used with somebody one had not previously met. Its sense would have been "I'm glad I bumped into you because..." (Or the reverse - "Ill met by moonlight, Titania" from "Midsummer Night's Dream"!)
The "Fall" is another US usage strange to our ears but was normal in the UK 400 years ago. Likewise the very archaic (except in Scots) "gotten" and so on.
