Last Friday, my eyes accidently started looking at a girl(American) in my Calculus class. She caught me at the same time. When she caught me, I kept looking at her. I felt like I was unconscious about what was happening. It was unintentional look. However, there was something about this 4 sec. accidental look. She felt it. I felt it. I don't know anything about her nor she do about me. How should I approach this? Need mature advice.
