What does this guy's body language say about me?
This guy kept glancing or looking at me whenever he saw me or got the chance to see me in his chemistry lab class. He never talked to me nor did he ever approach me, so I don't know him very well, and he doesn't know me. All he does is look wandering at everthing around him, including me. Only this one time when he was not busy, and I was looking to the side, he was staring at me non-stop for a couple seconds without taking his eyes off me with slightly raised eyebrows, and a hardly noticeable smile. (i noticed that when i had looked up later).
Why was he staring at me like that? Please give me an honest answer.
