While staying with a family, I found their teenage son, Davi

While staying with a family, I found their teenage son, David, aged 16, didn’t share his true feelings with his parents. If his parents were present when I asked him how he felt about things, he would look down or away or say something unrelated such as, "Today, I will go out. "or "Okay, I guess. "However, when we were alone he would open up and tell me how he felt. For example, while sitting at the dinner table, I asked him how he felt about his history class and the teacher. He thought for a moment but said nothing. I thought he was afraid to answer in front of his parents, so later I asked him again in private. He said, "On a scale (级别) of 0-10, it is a big fat zero. He is the most boring teacher I have ever had. "I asked him why he didn’t tell me this earlier. He said it was because his parents didn’t want to hear that. They just wanted to hear that everything was wonderful and they always told him to stop complaining.
This made me think a lot. My belief is that children are born with the desire to share feelings. I also believe they are born with perfect emotional honesty. Unfortunately, such valuable things are disappearing gradually. It really is a great loss, which I believe, will negatively affect both the children’s ability to know about themselves and their success in future relationships.
I see the situation as a missed opportunity, an opportunity for parents to get closer to their children, an opportunity to understand their children and to help them feel understood; however, communication gaps (分歧) have been made. Parents are more interested in "correcting" their children’s ways of expressing themselves than in getting to know their children.
