Last week on my last week of college I was staring into space and I was looking at the trash can and then later this girl in my class was standing by the trash can and she was looking at me and smiling but I just looked away. Then later I was staring at the wall and when I looked over I see her looking at me and smiling while she had her hands on her head but I looked away. Do you guys think she was laughing at me or something?
