When Maria del Carmen reads or writes, she changes the letters of place or confuses them with others, which is why her teachers reprimand her because they believe she is rebellious and capricious. Mari relates the days of her daily life in which, due to its peculiarity, she has to face the ridicule of other children and negative comments from people. But Mari doesn't do it intentionally, she has a difficulty that doesn't allow her to read and write like the others. She tells us her story, which unfolds in a time when dyslexia was not known and much less was known to need special treatment.
