- It is never obligatory in France to kiss a person you have not met before. It is still mainly reserved for relaxed occasions with family and friends of the same age, although growing more common between work colleagues who know each other well.
- It is acceptable, even commonplace, for straight men to kiss good friends or relatives.
- In most regions, you exchange two kisses, starting on the right cheek.
- It merely requires the lightest brushing of cheek to cheek, but at the moment of brushing you are expected to make a 'mwah' sound.
