When I was a sophomore, my academic performance in all subjects declined because I was very disappointing. I don't think I can take the college entrance examination any more, and I won't have a more successful life. But at this time, my head teacher just won't give up on me, give me lectures every day, chat with my parents every day, tell them my recent situation and help them educate and coach me. After a year of hard work by the teacher, I finally got what I wanted.

Now every year when I go back to my hometown, I will visit my high school teacher and bring some gifts. I think every time I visit her, it is actually an act of gratitude, because without his teaching and persistent education at that time, my life might have undergone earth-shaking changes, and I would not be as successful and perfect as I am now. It will be a lifetime, and such kindness will be remembered by me for a lifetime.
