Hello.. We should all know good manners. Manners are very important in a person's life.If you have manners you will have lots of friends or people who like you. If you meet anyone say hello, good morning, thank you or good bye instead of ignoring that person's presence which makes them feel disrespected. Do not be rude to people by teasing them or aying bad words to them like saying "YOU ARE SO MEAN" Do not cut someone's line while they are speaking but wait for your turn. Always be polite to everyone including adults or peers. Always share your things when someone is in need. Never take revenge from someone if they did something bad to you. Follow this if you want to have friends and if you want to be respected.
