When maintaining friendship, you should not completely ignore the inappropriate behavior of your friends. Healthy friendship is based on sincerity, respect and mutual support. If a friend behaves improperly： -You can choose the right time to express your views in a caring and respectful way -Set reasonable boundaries and clarify what is acceptable to you and what is unacceptable -Make judgments based on the severity of the behavior-minor shortcomings can be understood and accepted, but harmful or unethical behavior needs to be confronted. True friends will be willing to listen and think about your worries. Through honest communication, friendship may become stronger. Remember, supporting friends to grow and improve is more reflective of true friendship than indulging or ignoring problems.
