Two kisses or four?
As it happens in other regions of France, neither in Angers does a rule exist on how many kisses on the cheeks people should exchange when they do the bise.
It can be two kisses or four, but not one or three. I've realized that people kiss mostly twice, especially when they greet people they often meet, but four kisses are not to be excluded. If you don't want to get wrong, wait and see.
