Good manners represent our values concerning social style. Manners signal our respect for other people and are essential in gaining the acceptance of others. Two-year-old children playing on a slide will stand in line, respecting each other’s turn. If an aggressive child crowds in, the "line" will decide as a group whether to allow it or to shove him out.By the age of 2, a child is already expected by his game-mates to respect the rules of the game.And rules, like manners, define the behavior that others expect from us.
A、child who is either too aggressive or too retiring to follow the rules is labeled an undesirable by the other children.
