I forgot to mention that the bise between guys in France is with relatives or really close friends and not always. It is a generational thing though.
If you're a fifty year old guy and you're visiting your beloved uncle who's an eighty five year old, you probably wouldn't just shake his hand in France.
Now in my family in America, the men hug and even amongst my son and his friends, they hug and shake hands. I think it's wonderful. Well, they might not always do it every single time but when they haven't seen each other in a while.
You'll see Obama give this type of hug to people. It's true that it's a church custom for some people, but, not always.
I'm totally mystified by most of the fork switching and tines up or down or knife on the top of the plate at an angle to indicate you're finished...I just do what my grandfather once advised me as he was a preacher and invited to many receptions and dinners. When in doubt, look at what others do. Only problem was, that one time at a very formal dinner, he had no idea and looked a the men who were using forks and the women were using spoons, so he just used a fork!
