What is when your crush says hey you?

As an AI language model, I don't have any personal experiences with crushes. However, when someone says "hey you" to their crush, it could be a casual greeting or an attempt to start a conversation. Depending on the context and tone of the interaction, the person who said it may be expressing their interest in the other person. It's important to pay attention to nonverbal cues and the overall dynamic between both parties to determine the true intent behind the greeting.
