Tom was one of my classmate in middle school. He works very hard and was good in his studies. Our teachers liked him very much. So he wasn’t happy. He often looked very sadly. I wanted to know the reason. One day, I asked him, “What keep me so upset every day?” After talking with him, I learned that his father had never encouraged him. No matter what well he did in his studies, his father said he hadn’t been tried hard enough. I was very surprised after listening that. Encouragement is very important. Harmful words can be very harmful. Lucky, Tom’s father changed later and Tom finally became happy boy.
