1) Some pronouns change after prepositions. Yo becomes mí, and tu becomes tí.
Is there a "Formal" and "Casual" way to say either of these changed pronouns?
2) In the sentence, "Grité y grité pero la persona no hablió con mi", the part hablió con mi are incorrect. Is it just the hablió part, or are all 3 words incorrect?
Gracias
