Actually, "Buon Giorno" is a relatively formal Italian phrase that should be written separately (see "Ciao").
Good morning, Princess!
A popular Italian proverb states, "Chi si alza, ha la legge." This translates to "He who rises, has the law." In other words, you have the right to be successful if you put in the effort.
Good day! (in Italian: Buon giorno!)
A nice and helpful person, wishing him a life as clean and frost-free as the link he provided - what a blessing!
