до свидания ingilizce:

Bye bye!

In the United States, a wave means "good bye."

I waved good bye and then walked away.

She walked away without saying good bye.

How do you say "good bye" in German?

The end, so long good bye!

Good bye, and thanks.

Bye, see you tomorrow. "Oh, what's this? Leaving on the dot again?"

Bye!
