3. Avoid Talking about the War
This one should be obvious, but many visitors seem to forget that Germans tend to be extremely sensitive about the war, which most believe to be a huge embarrassment to their nation. The Germans are invariably tired of hearing about it, and it is considered extremely rude to bring up the subject with people you don’t know well. More importantly, never carry Nazi memorabilia or do the Nazi salute, even in jest: it’s an imprisonable offense in Germany.
