Lovers are not at their best when it matters. Mouths dry up, palms sweat, conversation 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.

We're a lukewarm people for all our feast days and hard work. Not much touches us, but we long to be touched. We lie awake at night willing the darkness to part and show us a vision.
