To start with, my alarm clock didn’t go off so that I got up late. By the time I got up, my father had already gotten into the shower. Then I rushed to the bus stop without breakfast. By the time I got there, the bus had already left and I had to rushed to school. When I got to school, my teacher had already started teaching and he was really angry with me. Then it was time to hand in homework, but I had left it at home. I was really embarrassed at that time.
One good thing was that my history teacher said something good to me because I had done a lot to prepare for this class. It was the only good thing for me yesterday.
