In No Mirror in My Nana's House, the writer repeats the title several times: "There were no mirrors in my Nana's house, no mirrors in my Nana's house." I think the author intended to teach readers that we don't need mirrors to reflect and know who we are. Reflections happen when we look closely at the people in our lives, our environment, how we interact within it, and all the beauty around us.
In Harry the Dirty Dog, the author repeats "dirtier" 3 times in a row: Harry got dirtier and dirtier and dirtier. He could have just said Harry got dirty, but the repetition reminds readers of the problem - Harry didn't like taking baths, and when he became extraordinarily dirty, he had to conquer his problem. I think that in the end, this led to understanding a bigger lesson: sometimes we need to do things even if we don't like to, either because it's good for us, it's helpful, or it's just the right thing to do.
In Wilfrid Gordon McDonald Partridge, the author repeated many different phrases. The one I chose was, "What's a memory?" he asked. By asking the question over and over throughout the middle of the book, the author reminds the reader of Miss Nancy's problem...losing her memory. The repetition also teaches us that there isn't one simple answer: throughout a lifetime we have many memories...each memory fitting into universal categories, yet personally unique.
