A man is judged by his outward behaviour and attitude. If he appears pleasing to others, people say he has good manners. This would include the way he dresses, the politeness of his tone and the social courtesies that he keeps up. For example, if he is respectful to his elders and to women, he will be well liked by society.
If he is arrogant and proud, no one will like him. Other people will tend to avoid him whenever they can. He will be an unwelcome guest in any company. Indeed, your manners decide how people will react to you. Very often your manners will also determine what opportunities you will be given in the life to go ahead and progress. Bad- mannered people will never be helped by anyone willingly. They will always be treated with disdain.
