I can speak endlessly of myself, to myself or to someone else, without ever succeeding in giving a complete and truthful picture of myself... The same thing happens with all these people who come to see me, and take so much trouble over their efforts to describe themselves to me with strict accuracy; inevitably I form an image of them which derives as much from myself as from them. If they go and see one of my colleagues he will certainly not see them exactly as I do. And they for their part will not show themselves to him in the same way they show themselves to me.
