A Mischievous Tortoise

A little bit of background: My grandpa has been told by the doctor that he can't/shouldn't drive. His muscles are slowly deteriorating and he is less capable of moving his foot from one petal to the next. One time his foot got stuck on the gas and he hit a post in a parking lot. My siblings and I don't ride with him when he drives. One of the last times I did ride with him, he sped up for every red light, then slammed on the brakes. That was a few years ago before the doctor told him to stop driving.

On this lovely afternoon my cousin and I found ourselves sitting in the back of my grandparents vehicle. The sun was beating down, and it was hot! Grandpa, who was sitting in the passenger seat, slowly stood up. Using the car as support he looked at the front door, checking for grandma. Then he looked back at us and smiled. Again he peaked over the top of the car checking for grandma. She was nowhere in sight. Moving as fast as he could and looking like an old tortoise, he made his way around the car. As he got to the driver side door he checked for grandma again. She still was nowhere to be seen. He opened the door and sat down in the driver's seat and started the car. Why he even had keys to grandma's car I don't know, but he did and they worked. I looked over at my cousin and closed my door. Grandpa closed his door too. Shortly after my grandpa closed the door he put the car into reverse and started backing up. My cousin decided to close his door too. When we reached the end of the drive way grandpa stopped the car. Then he put it in drive. I looked over at my cousin and shrugged my shoulders. Then I put on my seat belt. Very slowly we inched forward, but instead of returning to the previous spot, grandpa turned the steering wheel. We were headed out onto the grass of their front yard. My cousin started snickering. I felt like snickering too, but I could just picture the car smashing into one of their many trees. As we drove into the yard grandma came out the front door.
"Al what are you doing?" she shrieked.
"Hearing Aids," he yelled back.
"What are you doing? You aren't insured," she yelled.
"I need my hearing aids," he yelled.
"That's convenient," grandma said under her breadth. "What are you doing on the lawn?" she asked.
"Oh, I was just giving the boys some shade. They looked hot," he replied.
I couldn't take it any longer. Both my cousin and I started laughing. Luckily grandpa couldn't hear us. He didn't have his hearing aids. Grandma was too worried about grandpa in the drivers seat to notice.
