Here are some examples of these things. They tell you what a person with good manners does or does not do.

He never laughs at people when they are in trouble. Instead, he tries to help them. He is always kind, never cruel, either to people or to animal. When people are waiting for a bus, or in a post office, he takes his turn. He does not push to the front. On the bus, he gives his seat to an old person or a lady. If he, by accident, knocks someone, or gets in their way, he says "Excuse me" or "I'm sorry". 
He says "Please" when he asks somebody to help. He says "Thank you" when he receives something. He stands up when he speaks to a lady or an older person. And he does not sit down until the other person does. He does not talk or laugh loudly in public.
