"Tonight I love you in a way that you have not known in me: I am neither worn down by travels nor wrapped up in the desire for your presence. I am mastering my love for you and turning it inwards as a constituent element of myself. This happens much more often than I admit to you, but seldom when I’m writing to you. Try to understand me: I love you while paying attention to external things. At Toulouse I simply loved you. Tonight I love you on a spring evening. I love you with the window open."
— Jean-Paul Sartre, in a love letter to Simone de Beauvoir
