A smile on your face shows you are happy and friendly. Tears in your eyes tell other others that you are sad. When you raise your hand in class. The teacher knows that you want to say something or ask questions. You shake your head, and people know your saying “No”. You nod, and people know you are saying “Yes”. People can use body languages to communicate with others.
