The Carters were driving home from a trip.
Dad was driving.
Suddenly the car made a strange noise.
"Something is wrong with the car," Dad said.
"We need to pull off the road."
Mom looked worried.
"Do we have a flat tire?" she asked.
Dad got out of the car and checked the tires.
"All four tires look okay," he said.
"Is the battery dead?" Aunt Judy asked.
"No, I bought a new battery last week," Dad said.
"There must be something wrong with the engine."
Dad opened the car's hood and looked at the engine.
Mom looked at the engine.
Aunt Judy looked at the engine.
They all looked at each other.
No one knew what to do.
The kids began to complain.
"I'm getting hungry," Harry said.
"I feel thirsty," Emmy said.
"I need to use the bathroom!" Oliver said.
"I see a gas station with a mini-mart," Emmy said.
"It will have food, drinks, and a bathroom," Mom said.
"It will have gas too," Harry said.
"Oh, that's the problem!" Dad said.
Dad slapped his forehead.
"I forgot to fill the gas tank!"
