There are many precious medicines in the world, but there is a lack of regret medicine. Sigh... I'm so dizzy. I can't raise my head when I mention this. I really want to find a hole in the ground to crawl into--

That happened when I was in the third grade of elementary school. Teacher Xu announced the math test results and distributed the test papers to be taken back to parents for signatures. I only scored 86 points. This is the worst math score I've ever gotten in my "life." Parents’ signatures are also required. Doesn't this force me to go to a "dead end"? Hey~ I will definitely "eat" my mother's "fried shredded pork with bamboo branches" when I take the exam paper back. I was so anxious that I was like an ant on a hot pot.

I rolled my eyes. Now, I can slowly imitate my dad's handwriting. Hehe, I really deserve to be a "quick thinker".

......

The next morning, when I came to the school classroom, I took out the test papers to hand in. To my surprise, my father's "famous name" was no longer there. Oh, I thought about it, last night, because I just imitated my father's handwriting. Forgot to sign. I secretly "transported" the test papers to the bottom of the stairs. Taking advantage of this opportunity, there was no one around, so I started writing "shuashua". It was done in a short while. He took a deep breath and felt much more relaxed. As soon as the second class ended in the afternoon, Teacher Xu asked me to go to the office with her. ..."Yilin, isn't your father's name 'Wu Xujun'?" Teacher Xu said seriously. "ah". "Does your father use pencil to sign his signature?" "I..." My face suddenly turned red to the root of my neck. "Take the exam paper back and ask your father to sign it again." "I... understand.

"...

How wonderful it would be if there was a regret medicine in the world! I really regret it!
