What is she stares at me from a distance but ignores me?

It sounds like you're describing a situation where someone appears to be interested in you by staring from a distance but doesn't engage or interact with you in a direct manner. This can be confusing, and there are several possible explanations for this behavior:

1. Shyness or Introversion: The person might be too shy or introverted to make direct contact, even if they are interested in getting to know you. They might prefer to observe from afar rather than engage directly.

2. Mixed Signals: Sometimes people might not be fully aware that they are staring. They might be lost in thought or simply happen to look in your direction without any specific intent.

3. Curiosity or Appraisal: The person might be curious about you or trying to figure out something about you from a distance before deciding whether to approach.

4. Social Anxiety: If they have social anxiety, approaching or speaking to people can be daunting. Their distance could be a result of their anxiety rather than a lack of interest.

5. Existing Relationship Dynamics: If you already know this person, there may be existing dynamics or past interactions influencing their behavior, such as past conflicts, misunderstandings, or unspoken feelings.

6. Non-Interest: It's also possible that there's no deeper reason, and the person simply doesn't feel the need to interact beyond the occasional glance.

If you're interested in clarifying the situation, consider initiating a polite and casual conversation. This can help you understand their perspective and potentially clear up any confusion. However, it's important to respect their comfort levels and boundaries, and not to push for interaction if they seem unwilling or uncomfortable.
