In the modern people's lives, this is a very common phenomenon friends. From my point of view, I think it is because their parents and their children a lack of communication, which led to each other in some respects had a generation gap. So I personally think that parents should worry more about their children, whether living, learning, physical or mental should pay more attention to it. Because over time, slowly growing children may be receiving a different idea, and then, these children of their own will have some impact. Therefore, as their parents, you should pay more attention to what their own children some of the changes in time to help them get rid of the incorrect behavior and psychology. As children, we should be considerate of your own parents, may their thoughts or ideas with their own different, but the parents, after all, their parents, no matter how they do too, but are out of your love; so You learn to properly adjust all aspects of their speech and behavior; even if you feel you are right, but the presence of someone else's face, can not say some words of treason; because then, their parents will Unharmed. What generation gap or not and if you can find a place to sit down and talk about calm, look at those aspects of a problem, and then try to resolve. Generation gap is inevitable, but it depends on how you put that degree to reduce the gap. This requires that you can and good communication between their parents, and this is the correct solution.
