On Our Road Trip, I Realized My Husband Couldn't Drive

On our Memorial Day weekend trip, on the highway, my husband William suddenly asked me, "What does this button do?" I froze. That was the cruise control key on the right side of the steering wheel. He'd been driving this car for three years. I pretended to take a sip of water, and my hand shook so hard I spilled it all over myself. "Honey, what's wrong?" He reached over to wipe it off. I stared at the back of his hand, my heart pounding like thunder.
