Thoughts come to me in session, which I talk about right away, or else store up for days, weeks, or even years. Far from being set aside, they are all around us during the session and frame us. I illustrate what I am saying with the psychotherapeutical trajectory of an adolescent boy, first treated between the ages of thirteen and fifteen years, who then came back to see me at the age of eighteen. There comes a time when it is essential to express those thoughts that have never been mentioned. During the second part of his psychotherapy, when he is having trouble coming regularly to his sessions, I will put them into words.
