Formal Greetings

When you greet someone formally you try to show respect, and be very polite. That's why it's better to use longer sentences and more complicated structures. For example, instead of 'hi' you say 'good morning' and instead of 'thanks' you say 'thank you'. Besides, you can use such words as 'Sir' and 'Madam' that serve to give extra status and importance to the person you are talking to.
