A joke caused by homophonic; Primary school students' compositions.

I was too careless when I did my homework. My parents criticized me many times, but I just couldn't change it, and I often joked. For example, when I was doing my Chinese homework, there was a position called "()". Without thinking, I put the word "stand at attention" (which should be "firm") in brackets and it became "stand at attention". The homonym of "Ding" is "Mao", which makes people say: Why is your ass up? Another time, the teacher asked us to copy the lesson "Crows drink water". At first, the first sentence was "The crow was thirsty" ... "But I copied it as" A crow drank it "..." My mother corrected her homework and took it to my room. She smiled and said to me, "The crow has already drunk. Are you still thirsty?"? "I immediately realized: no, I made another joke. I quickly snatched the book from my mother. At first glance, I really wrote "thirst" as "drink". I also smiled helplessly, thinking: I must get rid of this bad habit and can't be careless any more. Students, don't be like me.
