Abby hadn't been staring. Much. If grading on a curve against several stalkers. She knew who he was in passing, in that Mat was the boyfriend of the guy Abby was casually sleeping with. Which was a very good reason to either avoid him entirely or be super sweet and polite to him with little space in between.

But she had to hear him fucking sing. Stupid sexy musicians. She knew that this reaction was not normal and had some very definite implications about who she is as a person. Still, when he looked over she just, hid that grin she had with one hand while waving shyly with her other.

She's doing really good at being cool about this.
