A person who is rude to you but nice to others could be described as selectively or conditionally polite. Their behavior suggests that they have the ability to be courteous and respectful towards others, but for some reason, they choose not to extend the same courtesy to you. This kind of behavior can be hurtful and confusing, as it indicates that they are capable of treating people well, but they specifically choose not to treat you in the same manner.
Possible reasons for such behavior could be:
Personal animosity: They might have personal issues or conflicts with you that cause them to behave rudely.
Jealousy or resentment: Their rude behavior might stem from feelings of jealousy or resentment towards you.
Misunderstandings: There could be misunderstandings or miscommunications between both of you that lead to their negative behavior.
Defensive behavior: They might perceive you as a threat or perceive criticism from you, which causes them to be defensive and respond rudely.
Social dynamics: Some people may act differently around certain individuals due to social hierarchies or group dynamics.
Personality differences: Certain personality traits or differences between you and the person in question might trigger their rude behavior.
It's essential to remember that their behavior is a reflection of their own issues and attitudes, not necessarily a reflection of your worth or character. If you encounter someone who consistently treats you rudely while being nice to others, it might be helpful to address the issue calmly and directly with them to gain clarity on their behavior. However, if their rudeness persists and negatively affects you, it may be necessary to limit your interactions with them or seek support from others to navigate the situation effectively.
