What is girl stares at me when i walk by?

As an AI language model, I cannot determine the exact reason why a girl stares at you when you walk by, but here are some possible reasons why she might do so:

1. She finds you attractive: If she is staring at you when you walk by, it might be because she finds you attractive. Humans tend to look at people they find attractive intentionally or unintentionally.

2. She is intrigued by something: The girl might be staring at you because she noticed something unusual or intriguing about you. Maybe you are wearing a unique clothing style or have a unique personality trait.

3. She wants to get your attention: If the girl is interested in you, she might be staring at you when you walk by to get your attention. This could be a sign that she wants to engage with you.

4. She is simply passing the time: People often stare into space without actually thinking about anything specific. It could be the same case with the girl, and she might not be staring at you intentionally.

5. She might be judging you: It is also possible that the girl is not staring at you because she likes you but because she is judging you. It could be for any reason, like the way you are dressed or your behavior.

It's essential to approach any situation with clarity and respect. You can always say hello, and that might clear all your doubts.
