“You’re such a cutie… You can live here with us forever if you want…” Little do Paul and Edith Guetz know that this effusive declaration to their baby in his cot will prove to be prophetic. 28 years later, and Tanguy is still at home. He’s brilliant (holds a degree in philosophy, Japanese and is finishing off a thesis in Chinese), charming (everyone loves him), attractive (apart from his fiancée Marguerite, Paul and Edith can’t keep up with the number of women he brings home) and just loves living with his parents. Although Paul is the first to joke about the situation and their “big baby”, all appears to be harmonious at the Guetz’s place. On the surface at least. In fact, Edith can no longer stand Tanguy. She’s even seeing a psychiatrist on the quiet and feels guilty about feeling like this about her own son. Fortunately, once his Chinese thesis is finished, Tanguy will be off to live in Peking. Edith is counting the days. On the outside, she’s the perfect loving, smiling mother, while inside she’s cracking up. Then Tanguy drops the bombshell about how he’s taking a year off from his thesis. It’s too much, Edith breaks down and divulges all to Paul who is astounded. No, she’s not happy. Yes, it’s true that in the past her only fear was that Tanguy would leave. Now her only fear is that he’ll stay, forever! The couple decide to horrify Tanguy, that way he’ll leave of his own accord. At first timid, they then discover they’re rather talented at making their son’s life hell. But when you’ve been “perfect” parents, making your offspring understand you want him out proves to be a more difficult undertaking than imagined. Not even the law can come to their aid; they’re going mad! No, these days, you can’t get rid of you son just like that. Particularly when he’s called Tanguy Guetz.
