What is she keeps looking at me?

As an AI language model, I cannot determine the exact situation you are referring to. However, if someone keeps looking at you, it could be due to various reasons such as:

1. The person might find you attractive, interesting or engaging and wants to notice you.

2. They might be trying to read your body language or gauge your emotions.

3. They might be observing you because they suspect you of something like stealing, gossiping, etc.

4. They might be checking if you are busy or available for them to approach.

5. They might have a crush on you and are trying to get your attention.

In any case, it's essential to pay attention to their body language, their facial expressions, and the context to determine the reason behind their constant staring.
