For some boys, living in the shadow of a brother or sister is a nightmare that stays with him for the rest of his life. He can never quite shake off the humiliation and feeling of inferiority. Comments like: 'Your brother would not have produced work like that' or 'You're not as talented as your sister' can ruin pride and kill ambition. Friends, too, can be used (or rather abused) as a model for him to measure up to, in questions like: 'Why can't you do as well as Jonathan?' But far from acting as a spur, adults who suffered these taunts as children say their childhood was tainted by them.
