请根据以下提示，结合你在生活中的一个事例，用英语写一篇短文。

In my school life , I have met many people who are really worth my recalling . But perhaps the most unforgettable person is my math teacher .

She was really open-minded and funny . Not only did she help us in class but also after class . I still remember one time I got a “B” in the final exam . I liked math best and the teacher took pride in me all the time , however , I failed . I felt so frustrated that I lost my energy and confidence . Then one day , I happened to meet her in the street , and my face turned red right away . To my surprise , she patted me on the shoulder with a smile , asked me not to give up and even encouraged me to worked harder . Later , she offered me a great many suggestions on learning math .In addition , she gave me every chance to show my thought about all kinds of problems , with whose help , I made great progress .

I will never forget the love and care she showed to me .
