Today's Italian lesson:
Ciao, mi chiamo ...: Hi, my name's ... (informal, just to say your name, to make it formal, just change Ciao with Buongiorno)
Piacere di conoscerti/la: Nice to meet you/How do you do
Come ti chiami (inf)/ Come si chiama?: What's your name?( for a suitable answer see the first sentence)
E' stato un piacere parlare con te/lei: It's been a pleasure talking to you (inf/form).
It is quite usual among friends too shaking hands while you introduce somebody. Quite rarely you exchange kiss while introducing for the first time. It could happen among very young people (teen agers and so...), just a couple of kisses on cheeks.
