What is is she checking me out?

As an AI language model, I do not know the context or specifics of your interaction with the person you mentioned. Therefore, it is difficult for me to provide an accurate assessment of whether or not the person is checking you out. However, if someone is checking you out, they may:

• Make frequent and prolonged eye contact with you
• Smile or look away when you catch their eye
• Mirror your body language or movements
• Position themselves closer to you or try to initiate conversation
• Compliment you or ask personal questions
• Use flirtatious body language or touch you lightly

Again, all of this is speculative and context-dependent, and it is important to keep in mind that the best way to know if someone is interested in you is to communicate openly and directly with them.
