In Italy, greeting an older stranger or an official with "Ciao!" and using Tu is considered presumptuous and disrespectful. Formal etiquette requires the 3rd-person singular pronoun Lei (regardless of whether the person is male or female!).
1. The Mystery of "Lei": Why Superiors Are Addressed as Feminine
Why do you address a male doctor or elderly gentleman as Lei (she)? During the Renaissance, formal address referred to abstract honorific nouns like La Vostra Signoria (Your Lordship) or La Vostra Eccellenza (Your Excellency)—all feminine nouns! The pronoun Lei was retained as an echo of this historic courtesy.
2. The Social Relationship Map: Who Gets "Tu" and Who Gets "Lei"?

|---|---|
| Friends, family, and peers | Professors, doctors, and lawyers |
| Children and teenagers | Elderly persons you don't know well |
| Fellow students at university | Bank tellers, police officers, and officials |
| People in gym / sports settings | First-time commercial encounters in luxury stores |
3. Direct Comparison: Daily Phrases in TU vs. LEI
| Greeting / Expression | Informal TU (Friends) | Formal LEI (Strangers / Respect) |
|---|---|---|
| Hello / Good day | Ciao! | Buongiorno / Buonasera! |
| How are you? | Come stai? | Come sta? |
| What is your name? | Come ti chiami? | Come si chiama? |
| Please / Here you go | Prego, entra pure! | Prego, entri pure! |
| Goodbye | Ciao / A presto! | Arrivederci / Buona giornata! |
4. The Magic Transition Phrase: "Diamoci del tu!"
In professional environments, Italian colleagues often start with Lei. Once rapport is established, the senior colleague will smile warmly and say:
"Possiamo darci del tu?" or "Diamoci del tu!" (Let's use 'tu' with each other!).
From that moment forward, formality drops and friendly warmth takes over.
