I had exams and so does the girl I like. After the exam, I was talking to my friends and could also see the girl I like with her friends. I looked at her a few times and noticed she was looking at me. At another time I looked both her and her girlfriend (from another one of my classes) looked at me. Then the girl I like looked a few times after and then all her friends looked at me. (All this looking by me was at intervals with me talking to my friends).
The girl I like and her friends didn't seem to be laughing or smiling at me but when they looked at me they just went back to talking.
I moved to the benches with my friends (where we have our lunch) and was looking at the entrance of where the exams were waiting for a friend to finish... I could see that the girl I like was looking at me from a distance (next to the entrance of the exam area).
What does all this staring/looking from the girl I like and her friends mean?
