From "ThePassion" by Jeanette Winterson

"Lovers are not at their best when it matters. Mouths dry up, palms sweat, coversation flags and all the time the heart is threatening to fly from the body once and for all. Lovers have been known to have heart attacks. Lovers drink too much from nervousness and cannot perform. They eat too little and faint during their fervently wished consummation. They do not stroke the favoured cat and their face paint comes loose. This is not all. Whatever you have set store by, your dress, your dinner, your poetry, will go wrong."
