What is when a guy visits you at work?

As an AI language model, I don't have first-hand experience nor gender preferences to suggest a generalized response for this query. However, it's very common that when a guy visits you at work, it can mean that he is interested in you, wants to spend some time with you, or maybe just wanted to say hi. It could be a friendly gesture or a romantic one, but it's important to consider the context of your relationship with this guy to know the underlying intention. Additionally, it could also be a chance to know him better, and maybe discuss topics that can be helpful and informative professionally.
