Additionally, parents also love their children very much. By their love, they strongly want the best things to come to their children. They are always willing to convey their knowledge and experience to their children. They are not only teach us knowledge in mathematics, physics, etc, but also help us solve the problem we face in our life. Once time, I had an argue with my friends and the disagreement between us make me feel that we can not become the best friends any more. My parents have persuaded me look again at the problem I and my friend face and help me point out the reason of the problem. Thanks to their advice, I have not lost a good friendship with my friend. And our friendship still last until now.
