2nd. Whenever they do meet, the man should be careful to look at her in such a way as to cause the state of his mind to be known to her; he should pull about his moustache, make a sound with his nails, cause his own ornaments to tinkle, bite his lower lip, and make various other signs of that description. When she is looking at him he should speak to his friends about her and other women, and should show to her his liberality and his appreciation of enjoyments. When sitting by the side of a female friend he should yawn and twist his body, contract his eyebrows, speak very slowly as if he was weary, and listen to her indifferently. A conversation having two meanings should also be carried on with a child or some other person, apparently having regard to a third person, but really having reference to the woman he loves, and in this way his love should be made manifest under the pretext of referring to others rather than to herself. He should make marks that have reference to her, on the earth with his nails, or with a stick, and should embrace and kiss a child in her presence, and give it the mixture of betel nut and betel leaves with his tongue, and press its chin with his fingers in a caressing way. All these things should be done at the proper time and in proper places.
