Greetings and goodbyes Deutschland v. USA
Formal or Informal? In Deutschland, the greeting we use depends on how familiar you are with the other person. If you do not know them, or for adults or people of authority, you should be formal. If the other person is a friend, family member or peer, you can be informal. This is different than in the US, where we are always informal.

Informal Morgen!
Formal Auf Wiedersehen!

Informal Tschau! Tschüβ!
