So, my response should address the confusion between the titles, mention the illegality of downloading pirated copies, and then offer legal alternatives like purchasing through legitimate platforms or checking out free library apps like Open Library or Project Gutenberg if Spanish translations are available. I should also remind them to support authors by purchasing books if they can, and if they can't, perhaps suggest looking for free resources or libraries. Need to make sure the tone is helpful and not judgmental, providing actual solutions instead of just pointing out the problem.
