Ok so basically I'm a university student and over the past couple of days I've noticed that a girl always makes eye contact with me and holds it for a long time when I pass her in the hall. Today I was even standing still waiting for something and I turned my head to find her staring at me while she was walking out of the building, she then made and kept eye contact with me as she passed. Now the thing is I don't think I have any classes with her, and the only time I see her is when I am walking by her in one of the uni hallways. So basically how would you approach her if you were in this situation and what would you say. Basically I'd like to know how I can take this situation and use it to get to know her or whatever.
