Same Biology class.  This never happens.  Do they sit together?  No.   

She sits with her friends.  He secludes himself to the other end of the room. 

She passes notes for 45 minutes to girls out of ear shot.  He obnoxiously complains that the teacher is too loud for him to nap.  She smirks and looks his direction.  He never turns around.  

Months go by.  She greets him enthusiastically while he barely gives her more than a grunt and a head nod in her general direction.  She fumes and does her best to internalize the rejection.  He hates her friends and the way she behaves around them.   

She called him an asshole—he grins towards the front of the room.

“I win,” he thinks to himself.  “See you after school.”
