The problem I had today

So today I was in school it was lunch. We were so noisy our yard duty told half of our class that we had to all sit on the wall. For information I am in 4th grade. So when my teacher came by she said that I made all of them sit on the wall. I said that I wasn't the only one who did it. I got my lunch and put my head down and drew a crowd. Then I started crying. I told her that I did not do anything. She said I did not have to sit on the wall. When recess was over my teacher caught me at lunch. I got in trouble .Then I was so quiet the rest of the day.
