What is when a girl is mean to you does that mean she likes you?

As an AI language model, I cannot generalize the behavior of every girl as their behavior varies from person to person. However, some girls may exhibit mean behavior towards their crush or someone they like as a defense mechanism or to get their attention. But it's important to remember that being mean is not a healthy way to express one's feelings, and it's always best to communicate one's feelings straightforwardly and respectfully.
