What is girl keeps glancing at me?

As an AI language model, I do not have any context or specific information about this situation, as it can be interpreted differently depending on different factors such as your relationship with the girl, the setting, and other variables.

However, generally speaking, if a girl keeps glancing at you, it could be a sign that she is interested in you or curious about you. It could also mean that she likes your appearance or something else about you. It's essential to keep in mind that glancing is not the same as starting a conversation or showing more explicit signs of attraction, and it could be just a coincidence or a habit of hers. If you are interested in the girl, you can try to initiate a conversation or smile back to show that you are approachable and open to interaction.
