Read the paragraph from a student’s report.

I awoke early this morning so that I could take the time to be extra careful in packing my backpack. This was the first time my family was going camping. Yesterday, my sister told me the campsite was three hours away from home. I wanted to be certain that I did not leave anything important behind. After I finished packing, I grabbed my sleeping bag and pillow and headed down to the kitchen for breakfast. I heard my parents and sister moving around upstairs as I poured myself a bowl of cereal.

Which sentence should be added to help introduce the narrator of the story?
