What is girl looks down when she walks past me?

As an AI language model, I cannot confirm the girl's intention or feelings when she looks down while walking past you. There can be several reasons why someone might look down while walking, such as shyness, avoiding eye contact, insecurity, or simply being preoccupied with their thoughts. It's important not to jump to conclusions and assume that the girl is interested in you, as this may lead to misinterpretations and misunderstandings. It's always best to communicate openly and respectfully to avoid any confusion.
