Some things I found quite interesting about this topic: In Laos people eat noodle for breakfast, in Germany bread or cereals. Both will ever change this habit. (Thanks to Gunnar Lindh for this!)
German people have the wedding ring in the right hand, will most other countries have on the left hand.
In Laos people always ask you where you coming from (or where have you been - Jao pai sai maa). This is not just pure curiosity. In former times, before big cities were established, every traveller was also provider of news. So it was always interesting to know where they come from and then ask for news. By the way, How is it going or the GEran "Wie geht es" is close to it as well.
