A woman who has vanity without affection will be pleased to hear of your past conquests, and regard them as victims immolated to her superior charms: to her, therefore, it is right to talk of them; but to flatter the heart, and give delight to a woman who truly loves, you should appear too much taken up with the present passion to look back to the past: you should not even present to her imagination the thought that you have had other engagements: we know such things are, but had rather the idea should not be awakened: I may be wrong, but I speak from my own feelings.
