My cousin is very rude. How should I educate him?

From an early age, I asked my children to be polite and yell at everyone. Parents are the best mentors for children.

Children's bad character is usually cultivated by their parents. It is generally not feasible to just say that he wants to be outgoing and independent and change him. After all, a child's understanding is limited, introverted and shy. The average child has no self-confidence. Give him more encouragement, let him express himself and give him more responsibility. Don't help him with everything Politeness must be done by adults, and children should feel that you are enthusiastic. Parents know manners, set an example for him and let him know that manners are very important. Praise the child immediately after calling others and encourage him to say hello to others in the future. Adults are role models for children, and children will do what adults do.
