When my mistress swears that she speaks nothing but the truth I believe her so that she will think that I'm a naïve youth, ignorant of the complex ways of the world – even though I know she's lying. So, to satisfy my vanity, I believe that she regards me as young, even though she knows that my best days are behind me. I agree with her lies without reservation. And so we're both concealing the truth from each other. But why does she insist on her lies? And why don't I insist that I'm old? Oh, it's best for lovers to pretend to trust each other; and older lovers don't like having their age pointed out. So I lie with her and she lies with me, and both being imperfect, we flatter each other with our lies.
