What is i catch him looking at me at work?

As an AI language model, I do not have access to external information and cannot provide personal opinions. However, if someone catches someone else looking at them at work, it could be interpreted in different ways depending on the context and relationship between the two people. It could be innocent curiosity, attraction, or professional interest. It's important to communicate openly and directly to clarify any misunderstandings and maintain a respectful work environment.
