假定你是吉安一中学生李华。在一位名叫Mrs. Worried的学生家长的微博上，你看到如下内容：

I am the mother of a sixteen-year-old boy. Recently I find it becomes more and more difficult to communicate with my son. He always sticks to his own way of doing things，refusing to listen to his father and me. The tendency of his being too independent really worries me. I simply don’t know what to do. Can anybody help me?

请给这位家长写一封信。要求包括以下要点：

1. 自己的看法；2. 陈述理由；3. 提出建议。
