翻訳 - ギリシャ語-英語 - ΓΕΙΑ ΣΟΥ ΤΙ ΚΑΝΕΙΣ? ΕΛΠΙΖΩ ΠΟΛΥ ΚΑΛΑ.

Since this isn't the requested translation but a go-between, I chose to do a verbatim translation even though the second part desperately needs a "you are " (I hope you are very well) and sounds strange to my ears either with or without the "you're"

Note that the tone is rather informal, as used between friends
