Guy's Behavior

Does this guy really look at me, or could I just be imagining it?

Where I work, there’s this guy that I find attractive, and who I can SWEAR secretly looks at me like he finds me interesting, but I’m not sure if I’m just imagining it or not. 🤔 One time recently when I happened to be dropping off something in his shared office (no he was not the only person in there), he was looking in my direction, smiling. But I’m not sure if seeing me was what made him smile, or if he was just happy I was dropping off what he and his colleagues needed at the time. And then just yesterday he looked in my direction in an empty hallway area, and I can almost swear that he smiled from seeing me, but actually I’m not really sure what his facial expression was, because whenever I run into him I feel so shy that I can’t even look at him. ☺️ And also one time when I just so happened to walk by a room he was in, he looked out in the hallway when I walked by, but I don’t know if he was looking at me, OR if he just looked up because he heard the noise of someone (me) pushing a loud cart down the hallway. So does anybody think this guy really looks at me, or that I’m just imagining it? 🤔🤔🤔🤔
