what's the best way to live quietly without having misunderstanding?

Don't think of yourself as too important. Know that it is okay to stand up for yourself, but without being rude about it. Be a good listener, try to hear what people mean, as well as what they say. If you can take a comment or an action as a negative, or as a positive, always choose to assume it was meant in the positive way. You have two ears and one mouth, God meant them to be used in that proportion. Always be willing to explain yourself and not think that someone means harm or evil to you.Do not say or do anything to others that you would not want done to you (the Golden Rule) Smile often, laugh much.
