We try here to submit a group of about fifty teenager’s calls towards a free telephone number (“ Fil Santé Jeunes ”) to an analyse based on semio-linguistic criterias. This work contributes to reveal a pretty large number of self-masking strategies of the teenager enunciator : mutism, insults, pseudo-questions, fictions. All the art of the adult listening would consist in wellcoming these masked enunciations to allow the caller to deliver his true questioning.
