1) What is the difference between "Ciao" & "Salve"?
2) When should we use them both?
Salve is more formal.
Why would you say hello AND good afternoon?
is buon pomeriggio common? i live in sicily and almost never hear it. Normally in the afternoon people still just say buono sera
Very rarely said in my experience as well. Which can make things kinda complicated/vague.
Salve is Latin!!!
