Since Odette never gave him any information as to those vastly important matters which took up so much of her time every day (albeit he had lived long enough in the world to know that such matters are never anything else than pleasures) he could not sustain for any length of time the effort to imagine them; his brain would become a void; then he would pass a finger over his tired eyelids, in the same way as he might have wiped his eyeglass, and would cease altogether to think.
