I read this statement recently (in 'England, England' by Julian Barnes, not anything written by a psychologist). How far do you think it's true? Of course upbringing affects us, but at what point does a personal failing stop being due to parental failing and start being something you should have sorted out yourself? Is it even possible for you sort these things out yourself, or are the effects permanent? Can you use the events of childhood to justify your behaviour forever?
