A note on speaking Italian
Use tu with friends and Lei with someone you address formally. A request with vorrei or potrebbe can soften the tone; it still helps to say what you need clearly. The examples label the situation so you can choose the appropriate relationship.
Read doubled consonants distinctly and keep the written accents. The English translation explains the intended message; Italian often chooses a different construction rather than matching each English word.
