I was at the library and I was telling my friend to save me a seat and I was waving hi at my friend and my crush was sitting in front and she was in the back and when I was waving at her he started to wave at me and he thought I was waving at him.Of course I was excited, but Im really confused because last year he was acting like such a jerk to me, but this year he is acting really friendly. What does this mean.
