Because of this you might find German men to be a bit shy as they are not as used to randomly talking to strangers.
They don’t usually know how to walk up to strangers and start conversations as they haven’t witnessed it happening around them.
This may also be why they like getting drunk and partying…In America it’s more common to approach people randomly and also to talk about random things.
Likewise, if you talk to them they will assume you do so because you want to get to know them, not because you are being polite (unless you are left alone with them in an uncomfortable situation, of course).
They will also most likely end the conversation if they aren’t enjoying it.
Everyone here tends to ask how you are doing and have a little chat with you without for that matter actually wanting to make friends with you. This means they get into much deeper discussions and they will reply with a lot more candor to your questions.
