“Bomanz had lived his lies so long he often lied to himself.”

Upon visiting the grave of Johann de Kalb, some years after his death, as quoted in "Baron De Kalb" https://books.google.com/books?id=40wyAQAAMAAJ&pg=PA96&dq=%22Would+to+God+he+had+lived+to+share+its+fruits%22&hl=en&sa=X&ei=2IoZVa3XLuyasQTXiIDoCg&ved=0CB0Q6AEwAA#v=onepage&q=%22Would%20to%20God%20he%20had%20lived%20to%20share%20its%20fruits%22&f=false (1827), by George R.

Context: I must be myself. I cannot break myself any longer for you, or you. If you can love me for what I am, we shall be the happier. If you cannot, I will still seek to deserve that you should. I will not hide my tastes or aversions. I will so trust that what is deep is holy, that I will do strongly before the sun and moon whatever inly rejoices me, and the heart appoints. If you are noble, I will love you; if you are not, I will not hurt you and myself by hypocritical attentions. If you are true, but not in the same truth with me, cleave to your companions; I will seek my own. I do this not selfishly, but humbly and truly. It is alike your interest, and mine, and all men's, however long we have dwelt in lies, to live in truth. Does this sound harsh to-day? You will soon love what is dictated by your nature as well as mine, and, if we follow the truth, it will bring us out safe at last.

Variant: Clinton lied. A man might forget where he parks or where he lives, but he never forgets oral sex, no matter how bad it is.
