Once they knew each other it was more difficult, because it is difficult to love those we know well. To be in love is to be curious. A thing is only beautiful if we do not have surfeit of it, perhaps only what is new is beautiful; in any case we can only love what is new. In order to love people we have got to know too well, we must first of all forget them, not altogether but very nearly. This they learnt during the fortnight. They didn't tell each other that they had learnt it; they were careful, that is, untruthful. To be able to love someone a long time one must lie, quite often to oneself, but mostly to the person one loves.
