Translation - German-English - Guten Tag und Auf Wiedersehen. Zwei Seiten ein...

Definitely not *greetings* but *aspects* or *facets* of the same meeting

Thank you.
I thought it might refer to the two greetings, which can be used within the same one meeting...

Tzicu-Sem

Two aspects of the same meeting.

Same thing: "OF" the same meeting.

'Good day' is the equivalent to the ones used in both languages.

In the german version, Zwei Seiten ein und derselben Begegnung, meaning "Two sides of one and the same encounter/meeting".

Hello could be "Good day" and goodbye - alltogether.
meeting - appointment or rendezvous, in my opinion, is better way to say the original meaning.

Good day/afternoon

not "hallo" but "good day"

"Gutten Tag" can be transled into English by using 'hello', 'good day', or 'good afternoon', indeed. But I chose to use 'hello' because it is the most common form of greeting when meeting someone.
If I used 'good day', it would sound very much like 'good bye', which is already in the text. It is true that 'good day' is used to render the exact meaning we find in German, but that happens in very formal contexts.
And I am reluctant to using 'good afternoon' because it refers to a certain time of the day only.
It is difficult to decide without a context...

"hello" is like "salut" in french.

Bonsoir trusia. En français, on dit "une rencontre" c'est un mot qui est féminin en français.

Mais cette page est celle de la traduction vers l'anglais, que j'ai demandée.

upsssssssss une gaffe ;P

merci))
