The English translation is below the Spanish paragraph.

Había un poco de diversión y días emocionantes en la escuela, ellos sólo no pasaron a menudo. Mi idea de un día escolar bueno entendía lo que estaba siendo hablado en la clase y no teniendo cualquier tarea. Pero esto no ocurrió. Tuve que inventar modos de entretenerme. Y muchos días que no trabajaron.

There were some fun and exciting days in school, they just did not happen often. My idea of a good school day was understanding what was being discussed in class and not having any homework. But that did not occur. I had to invent ways to entertain myself. And many days that did not work.
