The idea behind the International Kissing Day is that many people may have forgotten the simple pleasures associated with kissing for kissing’s sake, as opposed to kissing as mere social formality or prelude to other activities. International Kissing Day is not as commercialized as Valentine’s Day.
Cultural connotations of kissing vary widely. A kiss may be used to express sentiments of love, passion, affection, respect, greeting, friendship and good luck, among many others. The act of kissing has become a common expression of affection among many cultures worldwide. (from: Wikipedia and www.cute-calendar.com)
