House of D (2004)

On their son Odell's 13the birthday, graphic artist Tom Warszaw finally confesses to his wife why he fled Greenwich Village, NYC at that age to Paris. As a schoolboy, naturally sensitive, considerate Tommy was best buddy with 'adult' half-wit Pappass, father Duncan's Catholic school's assistant janitor. Smothered by his dependent mother, a dumb orderly, Tommy got 'parental advice' from a women's prison inmate. Together with Pappas, he saves up tips from their butchery delivery rounds. One night, Pappas steals the bike they were saving for. Tommy tries to take the blame, but ends up expelled as if the instigator. Even more tragic consequences follow.
