A fight in class

Today I fought with my friend because we were both mad at each other. In science class we were looking at a cell. So, I was trying to focus the microscope. But I couldn’t, so I passed it to my classmate. But he also couldn’t do it. I told him to pass it to the next person, but he said he wanted to look some more. Then the class ended. My friend said that she hadn’t looked at it yet. So she yelled at me. Then I yelled back. And that became a fight.
