This paper proposes a discussion about acting on the therapeutic relationship using the notions of playing and the “use of an object” formulated by Winnicott; the formulations of Ferenczi as the concepts of introjection and the “ability to feel with”, as well as the concept of cartography from Deleuze and Guattari. It discusses how to manage the meeting with individuals who confront the analyst with sudden questions, gestures and actions. I propose that the management of the acting considers that there is a call for a conversation in which “doing” is in question, and in which the playful dimension of activities without rules is employed as a necessary option.
