Often one has to come down to ‘kept’ persons, male or female, before one finds the hidden spring of actions or words apparently of the most innocent nature in self-interest, in the bare necessity to keep alive. What man does not know that when a woman whom he is going to pay says to him: “Don’t let’s talk about money,” the speech must be regarded as what is called in music ‘a silent beat’ and that if, later on, she declares: “You are far too much trouble; you are always keeping things from me; I’ve done with you,” he must interpret this as: “Some one else has been offering me more.”
