He doesn't even see the truck before it hits him, since he's listening to music and trying to get over the fact that he got a C on a test. It's not the end of the world. Even if his parents will make it out to be. And he really should have studied more. And... Ugh.
But the truck does, in fact, hit him from behind as he walks on the sidewalk. He's face down on the concrete, head twisted sideways, hurting more than anything ever has. He sees the truck continue on and collide with a tree.
There's been an accident.
Someone could be hurt. Someone should call 911.
...I'm hurt. Someone... Should...
It doesn't hurt for long. The paramedics try, but when your body is hit and then run over by a truck, there's not much anyone can do.
