“A bore is someone who deprives you of solitude without providing you with company.”

La solitude est certainement une belle chose, mais il y a plaisir d'avoir quelqu'un qui sache répondre, à qui on puisse dire de temps en temps, que c'est un belle chose. (Solitude is certainly a fine thing; but there is pleasure in having someone who can answer, from time to time, that it is a fine thing.) —Jean-Louis Guez de Balzac, Dissertations chrétiennes et morales (1665), XVIII: "Les plaisirs de la vie retirée".

Context: I got into bed, opened the bottle, worked the pillow into a hard knot behind my back, took a deep breath, and sat in the dark looking out of the window. It was the first time I had been alone for five days. I was a man who thrived on solitude; without it I was like another man without food or water. Each day without solitude weakened me. I took no pride in my solitude; but I was dependent on it. The darkness of the room was like sunlight to me. I took a drink of wine.
