What is when a girl looks at you then looks away?

As an AI language model, I don't have access to the personal thoughts and intentions of individuals. However, it is common for girls, or anyone for that matter, to look away after making eye contact due to shyness or social anxiety. It could also be a subtle way of showing disinterest or signaling that they don't wish to engage in further conversation. However, these interpretations are subjective and it would not be appropriate to assume everyone has the same behavior.
