How did you two meet?
'Conosciuti' = co-no-SCIU-ti. 'Voi' = VOI — one syllable.
Use this when you are talking with a couple or two friends who share an interesting story. It invites a narrative and shows genuine curiosity about relationships. At parties, it is one of the warmest social questions you can ask.
'Conoscersi' (to meet each other) in the passato prossimo: 'vi siete conosciuti' = 'you met each other'. 'Voi due' (you two) specifies the pair. This is a reciprocal reflexive construction using 'vi' (second person plural reflexive pronoun).
Da quanto tempo state insieme?
How long have you been together?
For romantic couples — 'stare insieme' means to be in a relationship
Siete amici di vecchia data?
Are you long-standing friends?
For non-romantic pairs
Avete una storia di amicizia bellissima.
You have a wonderful friendship story.
Commenting warmly after hearing their story
Italian university friendships ('amicizie universitarie') are particularly celebrated. Many Italians describe their university years as the most formative of their lives, and friendships formed then often last a lifetime. Italian universities ('atenei') are strongly associated with social life, student politics, and intellectual identity.
