　　Too Late to Regret It　　When I was a junior, I met a second-year student in my department. He wasn't tall or good-looking, but he was very nice, attractive and athletic. He had something that I admired very much. He was natural, warm, and sincere.
　　I disregarded （不顾） my parents' disapproval. We were very happytogether. He　picked me up from my dorm every morning, and after class we would sit alongside the　stream that ran through campus, or sunbathe （晒太阳） on the lawn. At night he would walk me back to my dorm. He came from a poor family, but in order to make me happy,he borrowed money from his friend to buy presents and meals for me. Our fellow students looked up to him as a role model, and the girls envied （妒忌） me. He wasn't a local, but wanted to stay here after graduation. I thought we had a future together.
　　However, when I got a part-time job during the summer vacation, people began giving me a lot of pressure, saying that a pretty, intelligent girl like me should find a better guy to spend time with.
　　This was also what my family thought. He spent the summer in his hometown, so I was all by myself. When he got back, I began finding fault with him. But his big heart and warmth soon drove all unpleasant thoughts away. However, I had no idea how badly I had hurt him and that things would get worse.
　　I had a good part-time job off campus that paid pretty well. With my good performance at school, I also got admission to graduate school at one of China's best universities. He, on the other hand, did not do so well at school or at work. I had to worry about his living expenses, job and scores.
　　Almost all my colleagues and friends advised me to break up with him. Then we had a quarrel last June.
　　He was in great pain, and my cold words and bad moods started turning him away.Graduation time was drawing near, and he said he wanted to go back to his hometown. He said that he couldn't put up with me anymore. I was shocked and looked at him in despair.
