ciao Milena,
as for the letter I, i didn't realize that I had failed with the example! "like" is the worst example that I could choose.so Nicola is perfecly right when he say that the sound is the same of the serbian "и".
returning on the greetings that I promised you in the last mail:
we have "buon giorno"=dobar dan (with the same uses of yours);
"buona sera"=dobro veče; "Buona notte"=good night; Buona mattina"='Dobro jutro' (we don't use it).
you already know "Ciao" it is more informal. the formal way to great someone is Buon giorno.
some simply questions:
come ti chiami?=What is your name?
quanti anni hai?=How old are you?
come stai?=How are you?
the situation here in Italy is quite good. our big problem for the moment is the high cost of life:since we begin to use Euro everithing is more expensive ! yesterday we had a very big strike to protest about work conditions, school reform, our bad economy(we have the last economic growth of the european union!). a part this, the rest is ok! our country is very beautiful to visit, the big city has a very good night life for youth and students . so you will came here with school next year; do you know more or less what you will visit?
Buona giornata (have a nice day)
ciao!
