No, seriously (lol), I am German and I love to be disciplined, serious, down-to-earth, no-nonsense and most of all ... orderly.
Even if I come to your house as a guest. Achtung! Be wary! Do not leave me alone waiting in a room. I might start rearranging things.
A table not set properly? A crooked picture on the wall? A book sticking out too much from the others on a bookshelf? Must be helped.
Nothing will be save from me and my corrections. Nothing. Nichts. Nix.
I am a German after all (no worries these days: not a Germ, that is sth different). It's cultural, genetic, morphic-fieldic, whatever. Fact is: I can't help it. Be gentle and forgiving please.
