Explanation
In Mexico, a single cheek kiss (often air-kiss or light contact) is a standard greeting among women, and between a woman and a man, at social gatherings. Men typically shake hands or give a pat on the back, but cheek kissing is widely accepted in informal or friendly settings.
Local Tip
When greeting a woman, offer your right cheek and make a light kissing sound; for a man, wait for him to initiate a handshake or hug.
How it compares elsewhere
Cheek kissing is not customary and can be seen as invasive; a bow is the standard greeting.
Cheek kissing (la bise) is the norm, but the number of kisses varies by region (typically two to four).
Cheek kissing between men is common, but between unrelated men and women it is strictly avoided in public.
