I recently found out that people in France do not hug people they've just met. Or even people they know, unless they are very close. That made me cringe, thinking of how the family all hugged a young man from France the first time he visited. He's here again, and actually gave me a hug on arrival -trying to be like the Americans. But I still cringe when he meets new people and they want to hug him. He hides any discomfort well. In this video, we learn more greeting customs from around the world.
