This is a short story for Rochelle Wisoff-Fields “Friday Fictioneers” which is a 100 word fiction piece on the photo prompt.
As the Johnson family stepped out of the car parked on the side of the road, they looked fearfully around. Just before the tire blew out they heard what sounded like a gunshot.
The sound wasn’t repeated, but a few people headed out of the little store by the filling station. One of them was an old-timer with a rifle over his shoulder. Everyone scurried out of his way.
“What the hell?” Mr. Johnson said.
Clem turned around, shot another bottle on the shelf and then pointed at their rear tire and fired.
“Grandpa! What are you doing?”
