What does it mean when a guy stares but doesn't approach?

Anonymous
I've noticed this guy keeps looking at me with a blank expression. At first I thought that it was just a fluke but its been numerous times. For example, one time I'm texting my friend and I look up to see if she's there and the guy locks eyes with me as he passes by, another time was when he stared at me for a few seconds before leaving a lecture, and the rest of the times have been just random locking eyes incidences. He also sat down beside me once instead sitting with his friend. He's an attractive guy but I'm just wondering why he's so shy or is he not interested?
