Say "Ciao" instead of Sera, Notte etc by magyarozag
In Rome, when you see someone or leave someone you should say "Ciao" which is relaxed and casual. Whereas if you go to Turin (Piedmonte, Northern Italy) you should greet by saying "Buongiorno", (Good Morning) "Buonasera" (Good Evening) or "Buonanotte" (Good Night). It is only in a few cases in Turin someone will say Ciao. And only for meetings, conferences and formal occasions in Rome where Buongiorno etc are used.
