I have a friend who has a deep friendship with me, just like the deep sea; Her friendship with me is very strong, just like a bottle of mellow old wine; Her friendship with me is very fragrant, just like a flower that never withers! We often play together and call each other by their nicknames. We are happy every day.

But one day, we had a big contradiction because of a small thing.

It was July, the hottest day of the year. In the blue sky, the sun is hanging like a fireball, and the clouds floating in the sky seem to have been burned by the sun and disappeared without trace. The sun was burning, and I was sweating. "Hi!" A voice sounded in my ear. I turned my head and saw that it was my good friend! I also said hello to her, thinking that my homework has not been completed yet, but I don't want to leave my good friend, so I invited her to my home to do homework.

"Hello, auntie!" She greeted my mother as soon as she entered the door. I thought to myself, "This friend is a good friend!"! Not only polite but also good at learning. I sat with her in the study doing math homework. "Xiaoling, how much is the answer to this question?" She came up to me and asked. "This way? It should be 72," I said. "No, it should be 56!" She scratched her head doubtfully. "It's 72, you are wrong," I said confidently after checking again. "No, I think it's 56!" She insisted that her answer was right. "No! Look again!" I argued. In this way, we can't stop arguing because of this problem. She slammed the door out angrily, and our friendship broke down.

The next day I went to school. As soon as I entered the door, I met the "good" friend who was quarreling yesterday. I thought to myself: Today is really a narrow road for friends! He walked straight to his seat without thinking. The first one is math class. The teacher told the question, and the answer... is 72. After class, I still didn't talk to her, just sat down on the seat and opened the math book. I saw a piece of paper filled with words in it. I was curious and picked it up. As a result, mischievous tears could not help jumping out, and immediately tears filled his eyes. Why? Because that piece of paper was written with her sincere words:

"Hello, my friend. I'm sorry. I shouldn't have had a hard time with you yesterday. I should have listened attentively to you about why the answer is 72, rather than blindly believing in myself. Let's make up? It's a bad feeling to be separated like this."

After reading this note, I looked at her. Those apologetic eyes were looking at me! I was also very sorry to go over and said to her, "It's OK. In fact, I have something wrong with this matter. I should correct you in time, instead of arguing with you. Let's make up!" She nodded without thinking

Since this incident passed, she and I have never been separated for some trivial things. We also know that friendship is the most difficult thing in the world. So that separation made me unforgettable for a long time!
