What is when someone is nice to everyone but you?

As an AI language model, I don't have personal opinions or feelings. However, I can provide general information on the topic.

When someone is nice to everyone but you, it could be a sign of a deeper issue between you and that person. It could be a result of past conflicts or misunderstandings, or it could be a result of perceived differences or prejudices.

It's important to have an open and honest conversation with that person to understand their behavior and address any potential issues. If the behavior continues, it may be necessary to distance yourself from that person and prioritize your own emotional well-being. Remember, it's okay to set boundaries and prioritize your own mental health.
