I totally understand why parents feel so uncomfortable, but there's no need to worry about. We should consider parents' original idea, they were intended to ensure that we didn't get into bad habits, and they may want to understand our study, life and thought. we should communicate with parents and tell them more should trust their children. If you think parents have difficulty with the interview. Can write letters or frank told them to your own point of view, this can know more about each other. Better to deal with this matter.
