As the saying go, treat others as you would like to be treated.If we want to be treated well, and we should treat others well too.
Two years before, I was admitted to a high school.I felt proudly and superior.Therefore, I always looked down upon my classmates who turned for me in their studies.One day, Tom asked me help him work out a math problem.I glanced at it, and said, “So easy.What foolish you are！” On hear it, he said angrily, “I won't ask you again.” I was shocking.Only then did I realize why I was so unpopular with my classmate.From then on, I tried to treat them equally and helped them with all my heart.
