Kissing goes by favour. [ Proverb ]

As winds come lightly whispering from the west.
Kissing, not ruffling the blue deep's serene. [ Byron ]

Lord! I wonder what fool it was that first invented kissing. [ Swift ]

Advice is like kissing: it costs nothing and is a pleasant thing to do. [ H. W. Shaw ]

Teach not thy lip such scorn; for it was made for kissing, lady, not for such contempt. [ William Shakespeare ]

The Greeks adored their gods by the simple compliment of kissing their hands; and the Romans were treated as atheists if they would not perform the same act when they entered a temple. This custom, however, as a religious ceremony declined with paganism, but was continued as a salutation by inferiors to their superiors, or as a token of esteem among friends. [ Disraeli ]
