Germans are said to be very methodical, orderly and tidy.
A German proverb goes: Ordnung muss sein. Literally: Order must prevail. Or closer to an English proverb (and possibly describing cultural differences): Orderliness (or tidiness) is next to godliness.
I, on the other hand, live according to another saying:
Tidy people are just too lazy to look for things.
