I have had a crush on this one guy for a while now, and its pretty obvious. So he most likley knows. And this one day, I was sitting outside of school waiting for my friends so we could walk home. Anyways, while i was sitting there alone, he walked up and stood a few steps infront of me and just stood there staring at me. I was looking the other direction but i could see him out of the corner of my eye. I turned and gave him a slight smile, he then smiled was about to say something, rubbed his neck then walked away. Do you guys have any ideas on what he was trying to do?
