I think all people should get along. For example, one day you might need help and they won't be there to help you. You should always listen to the law. Also, you should always treat people the way you want to be treated.
One way to talk to each other is to ask for help. One day you might be walking and need help finding your way home. If I see another person standing at the bus stop like he is lost, I would help him. If a car broke down, I would help the man to fix the car.
The law is a very important thing to listen to. Like if you are walking down the road and the sign says "stop" and no car are going, you better not walk or you will get hit. Say if you try to out run the cops, if they catch you, you are in big trouble. Say if you try to shut the cop up you will be in big trouble.
Another thing that is important about communication is treating other people the way you would like to be treated. Like if you are mad, you would want somebody to treat you right.
