" There is a foolproof way to distinguish peer-distorted counterwill from the genuine drive for autonomy: the maturing, individuating child resists coercion whatever the source may be, including pressure from peers. In healthy rebellion, true independence is the goal. One does not seek freedom from one person only to succumb to the influence and will of another. When counterwill is the result of skewed attachments, the liberty that the child strives for is not the liberty to be his true self but the opportunity to conform to his peers. To do so, he will suppress his own feelings and camouflage his own opinions, should they differ from those of his peers.

Are we saying that it may not be natural, for example, that a teenager may want to stay out late with his friends? No, the teen may want to hang out with his pals not because he is driven by peer orientation, but simply because on occasion that's just what he feels like doing. The question is, is he willing to discuss the matter with his parents? Is he respectful of their perspective? Is he able to say no to his friends when he has other responsibilities or family events or when he simply may prefer being on his own? The peer-oriented teenager will brook no obstacle and experiences intense frustration when his need for peer contact is thwarted. He is unable to assert himself in the face of peer expectations and will, proportionately, resent and oppose his parents’ desires. "
