1) Greeting
The simplest thing to say is "Good morning," "Good afternoon'" or "Good evening." This greeting is given to one whom you know only slightly, or to any one you are passing quickly. "How are you" is usually used when you are not in such a hurry. No answer is expected other than " Fine, thank you." "Hello' is the commonest form of greeting between good friends.

2) When a Man Raises His Hat
If you are wearing a hat which can be taken bold1 of easily, it is customary2 to raise it slightly off your head when you greet a girl or a woman.

3) When to Shake Hands
It is customary to shake hands when you first meet someone. And usually friends shake hands when they meet after not having seen each other for some time. However it is not necessary to shake hands.

4) Use the person's Name
It is always good form to use the name of the person you are greeting. You might say, "Good Morning, Mr. Moncrieff" or " Hello, Franklin." A person's surname3 should be used unless he is good friend or school-mate.
