What does the little boy in the little photographer think while crying?

I was too careless to finish the task, which delayed Gorky's precious time. I can't explain to my classmates when I go back. The little boy felt that he had a bad life and began to cry.

I was so careless that I forgot to bring my film, which also delayed Gorky's precious time. When I go back to school, my teachers and classmates will look down on me. I can't be so careless anymore. I want to get rid of this bad habit.
