Sometimes the awareness that one is distrusted can provide the necessary incentive for self-reflection.

But distrust of one who is ③ sincere in her efforts to be a trustworthy and dependable person can be disorienting and might cause her to doubt her own perceptions and to distrust herself. Consider, for instance, a teenager whose parents are ④ suspicious and distrustful when she goes out at night; even if she has been forthright about her plans and is not ⑤ breaking any agreed-upon rules, her identity as a respectable moral subject is undermined by a pervasive parental attitude that expects deceit and betrayal.
* forthright: 솔직한, 거리낌 없는 ** pervasive: 널리 스며 있는
