There is an essay about how I get happiness in helping others, including Li Nainai! Give him an outline.

I saw other students trying to do the topic: "What's wrong with you? I'm so happy. After borrowing a ruler, I am much calmer. Each of us has helped others and received help from others. Seeing that there is not much time left, I am almost crying and my mind is blank. I think I got high marks. This little thing made me understand that no matter how big or small things are, the remaining problems seem to be much simpler. It's a pity not to do such a simple question. I was in such a hurry that I found that I forgot to bring my ruler. When the teacher announced the results. When I finished the problem of drawing a line segment, I quickly finished the problem of drawing a line segment? Without a ruler, I don't know how many centimeters this line segment has been drawn. I will try my best to help those who need help in the future. For those who have difficulties and need help, my deskmate Zhu Yixin seems to be able to read my mind. She lent me her ruler immediately after listening to it, so I took the time to finish the test paper and made a pencil writing sound from time to time. When I opened the pencil box to get a ruler, I asked me, I am very grateful to Zhu Yixin for helping me: What should I do? Getting help from others is the happiest thing. I still remember one thing clearly. That was the math final exam last semester. Just when I was in a hurry? " I told her I didn't bring a ruler.
