When dealing with others, follow a basic rule: Do not do to others what you do not want others to do to you. You can describe your feelings with sincerity, provided that you are not aggressive, and that you are careful and respectful in your assessment and judgment of others. Many young people mistake caution and respect for hypocrisy, and rudeness and narrowness for authenticity, unaware that harsh words have unintentionally hurt each other. So before speaking, please stand in each other's position to think, mature people, say anything will make people feel comfortable.
