Sketch (library cruising)

I sketched this at the library. The guy on the right kept trying to start conversations with the girl on the left. She was polite. She would listen to whatever he was talking about, then put her headphones back on. After a while, he got up, walked away and came back a moment later, looking pretty nervous. He stood beside the girl, pointed towards the exit and mentionned that he was leaving. She looked back down at her book and quickly shook her head like she was trying to shake a fly away. Can't blame a guy for trying, but from the look on his face, he won't be trying anything again soon.
