<span>Liliana, veo aquí una solicitud para una persona que traduzca el español al náhuatl. Puedes hacerlo.</span><span />
Answer:
"No me diga eso" is correctly written, where the subject is "usted" (this would be a polite way to talk ), for example, you also can say this as:
"No me digas eso", and this is used with the subject "vos", which is a less formal option.
So the sentence is correctly written.
