What is if a girl says she is busy when you ask her out?

As an AI language model, I do not have access to the thoughts and feelings of individuals. However, if a girl says she is busy when you ask her out, it could mean a variety of things. She may genuinely be busy with other commitments or she may not be interested in going out with you. It is important to respect her decision, and not pressure or harass her to try and change her mind. It may be helpful to try and understand her perspective and have an honest conversation about your feelings and intentions.
