Flattery.
This is a powerful weapon in the art of making love. Never lived there yet man or woman but what in some way or other could be flattered. The great point is to know in what way to use it. There is a time and a place to use it. A young lady will feel flattered if you get a chance, young man, to tell her mother about the good qualities of her daughter; never fear but the daughter will hear of it, for women cannot keep a secret.
