Cultural Tip
In Italian, adding 'per favore' at the end of a request softens the tone and shows respect. 'Fammi sapere' is a common, informal way to ask for an update; in very formal contexts you might use 'Mi faccia sapere' instead. Also, Italians often specify the exact day rather than a vague deadline, so pairing the request with a specific date (e.g., 'venerdì 12 aprile') can sound even clearer.
