a classroom setting

he sat there, in the back left of the class popping his knuckles and chewing on a black pen cap. he was tired and it showed. in his eyes, in his face. he looked awkward sitting in the desk. his large figure was much to big for the molded blue plastic chair attached to fake wood. he wasnt listening to the teacher. no one was. a class of 40 and almost everyone had their head on the textbook in front of them. thats the only reason i noticed him, i was able to see him for the first time. he was staring at something just beyond the clock with no expression. he wasnt even blinking.
