This girl in my class goes nuts daily

This one girl in my art class is always listening to her spotify playlists and just staring at her background. What's funny about it is how she listens to a song for 30 seconds and then skips to the next song. She also stares at her background and it's like sonic the hedgehog characters. When she does this she rocks back and forth in her chair like she's rocking out or something but she does it even when she's not listening to music. It's just really funny and I thought I would share this.
