What caused the children to fight?

Boys used to fight when they were children. We made up after the fight, and then we fought. It's all true. Girls rarely fight, and it is difficult to make up after fighting. I got into a fight in my freshman year and lost my earliest deskmate friendship in primary school ~ I later called it: a war caused by an eraser. Senior year.

During the Spring Festival, my aunt came to see me from other places and bought a lot of stationery, including two beautiful strawberry erasers. At that time, there were not as many kinds of erasers as there are now. Fruit erasers just appeared, and they were not sold around the school. It's even more embarrassing after school, the most beautiful eraser! Then one day after class, I found that the eraser was gone and the pencil case was rummaged through. After class, the teacher dictated new words. I borrowed an eraser from my deskmate when I wrote the wrong words, and found that she was actually using a strawberry eraser.

Ask her after class, did you steal my eraser? No, this eraser was given by her brother. I said you lied, but you didn't last class. Give me back my eraser! The students at the next table also said, that is, give it back to me. So I returned it. A few days later, the eraser disappeared again. Surprisingly, I found that my deskmate used half a strawberry eraser. Did you steal my eraser again? Say no! Ah, Xi ba ~! I am so angry! You stole my eraser and gave it back to me without telling me? ! Ow ~! I can't stand it! It's no use talking! Finish the fight first! Suddenly I beat my chest until the bell rang. The teacher found my deskmate crying and punished me for standing for a class.

So the next day I beat my deskmate again. On the third day, the teacher transferred a new deskmate from Class Two and transferred her to Class Two. I once met her in the toilet and said hello: hi ~! As a result, she ignored me. Although she didn't meet many times, she didn't talk to me in the whole elementary school. I haven't seen each other since junior high school, and I went to different schools respectively.
