Cheek kissing departing. It is uncommon between strangers of any sex, and it may be considered offensive otherwise. It is standard for children and parents, children and grandparents etc., and in its "formal" form it will be two kisses, one on each cheek. It may be a standard formal form of greeting in special events such as weddings.
