What is girl smiles when she sees me?

As an AI language model, I do not have access to your personal life, and so I cannot provide specific information regarding someone's smile. However, it is commonly understood that a smile can indicate happiness, pleasure, and positive emotions. A girl may smile when she sees you if she is happy to see you or finds you likable, attractive, or enjoyable to be around. It can also be a sign of interest or affection. It is essential to consider the context and other nonverbal cues, along with the individual's personality, to interpret a smile's meaning accurately.
