As the saying goes, "it's too late to regret it", but when I got here, it became "a slip of the foot will make an everlasting regret"

I have always been a careless child: once, I came to the school gate and found no one, only to realize that I had looked at the time early; Another time, my mother asked me to take a bus to my grandmother's house, but I didn't expect to get on the wrong bus and put on a modern version of "going south"; The most ridiculous thing is that time, my mother and I went to the hotel for dinner. I wanted to go to the bathroom, but I walked into the ladies' room. However, two things happened in succession the other afternoon, which completely changed me.

It was a sunny afternoon and we had a Chinese exam. As soon as the bell rang, I returned to my seat with trepidation and thought: Will the examination paper be difficult? At this moment, the teacher came in and handed out the test papers. I quickly looked at it, ah! It's as simple as "1+ 1=2"! I finished it at once. As soon as the class was over, I handed in my test paper with confidence. I thought I could get more than 95 points in the exam, but when I was proofreading with my classmates, I suddenly became blindsided: the sixth question asked to check "Yes", but I crossed out "Wrong", which was worth 3 points. The teacher also said that this situation should be doubled. Oh, my God! I am in pain.

The second class is math. The teacher asked us to do exercise books, and especially stressed that because the topics are simple, we students with excellent math scores can't make mistakes-we will be punished if we make mistakes. Mathematics is my strong point. I finished all the questions quickly, and my heart was beautiful: the teacher didn't lie, it was really simple.

I didn't expect the teacher to call me when I changed my class. I thought I was going to praise me, but I found that I got three questions right, but I copied the answers wrong. The teacher's pointer held high and dropped gently, but his eyes were as heavy as a thousand pounds. These three times not only hit my hand, but also hit my heart. I swear that I will never be careless again.

I believe that if I am not careless, I will not write wrong words; I believe that if I am not careless, I will not make a mistake; I also believe that a person who is not careless must be a smarter person.
