Do you think that it is possible for a child to really to know one’s parents? Explain

I think that it’s possible for a child to really know one’s parents. Maybe, many children think that I know my father or mother very well because they live together in the same place and spend their most of time to their parents. With this feeling, each child advocates that he/she knows all the ways of his/her parents if compared to other relatives or friends of these parents. However, if they start to grow, they understand the reality. They recognize the truth which related to knowing their parents. As in the reality, each child knows only the physical appearance of his/her parents well. However, they don’t know their parents’ inner world because parents always not try to show their stress and boredoms to their children. With it, they don’t affect their children negatively because, in general, they like their children and they don’t want to break their motivation.  As a result of these conditions, we can’t easily say that each child knows one’s parents very well in the terms of parents’ psychology.
