Rule reminder

Common reported speech errors: 1) Forgetting pronoun shifts (tu→lui/lei, io→lui/lei, noi→loro), 2) Wrong tense backshift (using present instead of imperfect, or passato prossimo instead of trapassato), 3) Forgetting demonstrative/time expression shifts (questo→quello, qui→lì, domani→il giorno dopo), 4) Using indicative where subjunctive is required.
