This weekend, someone was explaining me the right way of receiving visitors. When someone comes to see you, the very first thing to do is to give them something to drink. This is called “l’eau de l’étranger”, or the foreigners water. Only after having offered your visitor this is it allowed to inquier about the reason for their visit.
I found this quite illustrative of two important points: the nature of the climate here, which is sure to make you arrive thirsty. But also a simple but strong recognition of importance of water before all else.
