What is what does it mean when a guy stares at you from across the room?

As an AI language model, I don't have personal experience. However, generally, when a guy stares at you from across the room, it could be a sign that he finds you attractive and is interested in getting to know you better. It could also mean that he is simply curious about you or finds something about you intriguing. However, it's important to note that staring can also be intrusive and inappropriate, so it's important to pay attention to how the guy is staring and how it makes you feel.
