People all over the world agree that being well-mannered really means being kind and helping others, especially to those older or weaker than ourselves. If you remember this, you will not go very far wrong.
Here are some examples of the things that a well-mannered person 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 animals. When people are waiting for a bus, or in a post office, he takes his turn.He does not push to the front of the queue. In the bus, he gives his seat to an old person or a lady who is standing.If he accidentally bumps into someone, or gets in their way, he says, "excuse me" or "I'm sorry".
He says "please" when making a request, and "thank you" when he receives something. He stands up when speaking to a lady or an older person, and he does not sit down until the other person is seated. He does not interrupt other people when they are talking. He does not talk too much himself. He does not talk loudly or laugh loudly in public. When eating, he does not speak with his mouth full of food. He uses a handkerchief when he sneezes or coughs.
