The wide stare

All yesterday I was wondering how to write about the young girl on the train who was signalling what might have been disgust to her even younger sister when a thick set boy shoved back one of the seats near them and then flung his body onto the vinyl in a way that might have expressed how he just does things and doesn't complain -- just as, in company, he will nod to his friends as if to agree to something risky even as his thoughts are taken up with the wide stare of several nearly teenage kids who might be watching from a window on the other side of the street. It was not easy, I was thinking, because the girls were soon looking at something in a plastic casing that the older one had taken from her bag.
