"Unable to rid myself of it, since I heard your song humming ever in my head… I hoped that a new impression would efface the first, and the first had become insupportable. I sought you. I saw you once more. Calamity! When I had seen you twice, I wanted to see you a thousand times, I wanted to see you always. Then— how to stop myself on that slope of hell?— then I no longer belonged to myself."
- Victor Hugo, The Hunchback of Notre-Dame
