I think that every well educated person should have good manners. You should be polite with all people if you want to be treated well. You can*t use  dirty slang in your speech. You should do only good deeds  

Every polite person has good manners. Such person is never rude to his/her classmates and teachers. He or she doesn't interrupt people and doesn't forget to say 'thank you'. If you have good table manners, you sit up straight, don't eat with your fingers and don't talk with your mouth full.
