Waiting at the Stoplight

Three acts in 120 seconds

Act 1. 
The light turns red as I reach it. I put my foot down on the pavement to balance. To my left on the sidewalk corner are two middle school boys, one tall and one short, who seem to be waiting. Behind me to my right, visible in my wing mirror, are three kids about the same age, two boys and a girl, also waiting. It is the second day of the school year.

Act 2.
The tall boy on the corner walks to the group of three kids, hesitatingly at first, then more confidently. He says something to them and they talk quietly. The short boy is looking at his phone, steadily, to all appearances totally absorbed.

Act 3. 
The short boy starts walking to school, staring at his phone. The four kids behind me are still waiting, for what? The light changes. I drive on.
