the guy i like was Canto some random song (replay) really badly might i add, in class. it seemed like he was looking at me for approval and when i didn't acknowledge him he'd get louder o just go really quiet. Mean anything?

It probably means that he was looking for ur approval and when he didn't get it it hurt him.so he either got louder to try and ignore u,or he went silent because he was hurt.not to make u mad o anything but that's the way it is.
