I have seen this guy around campus and I started to say a casual "hi" to him, usually I just get a smile and a "hey" or a nod back. The last time I said "hi" he hesitated then asked me how I was doing? I said "im good, thanks". Then I walked off. I kind of have a crush on him but was wondering if he was initiating a conversation cuz he might be interested? If you weren't interested wouldn't you just be like "hey" and skidaddle off. I don't know maybe im reading too much into it. Oh and I also saw him staring at me in a lecture hall. Not sure if it's because I turned around and he just happened to look my direction, but he was holding a stare.
