Besides van Gaal being famous for translating the rich Dutch proverbs into English/German there is some merit to the first post. I've notices since moving from Zeeland (province, sparcely populated) to the Randstad (Near The Hague, city style) some years ago, that in Zeeland we used a lot more proverbs in common speaking language than people do in the 'city'.

But that might just be me 'pulling my own plan'.
