PLEASE READ: Was This Really Cute Girl Checking Me Out?

Last week in cl, I walked in and saw this very cute girl sitting there. When I looked at her I had caught her looking at me and she quickly looked away. Today I was sitting behind her and to the left, and at one point she turned around and looked right at me for about 3 or 4 seconds, and I held her gaze for that time. After cl I decided to get some food at Tim Horton's on campus (which is about 3 minutes walking distance from the clroom) and what do you know, she ended up right behind me in line. It might just be coincidence, but I don't know. I didn't say anything because I got really nervous, I'm a pretty good looking guy but a bit shy when it comes to girls lol, not being y just stating the situation. About 2 times that day I would be walking through the hall and I would notice her and I would look and she would look back. It's like we're both aware of each other's presence (even though we have never formally met or talked). Any opinions? I'm pretty sure she's interested at least a bit, but I'd like some opinions. thanks!
