ok we already have german and english anyway, so i'll do it in italian, very important for all those of you going to mugello or misano:
How are you? - Come stai?
Hello/byebye - Ciao! (or also: buon giorno, salve etc. and arrivederci)
good morning - buon giorno!
I'm a fan of valentino rossi - Tengo per Valentino Rossi or Tifo Valentino Rossi
Stoner sucks: Stoner fa schifo.

haha.
Vale is the best - Vale è il migliore!
Vale is great - Vale è (un) grande!
I love you - Ti amo
haha...ok enough now.
