Train passenger was flirting with a young lady, but things got crazy when the lights went out

Archie and his project manager board a train headed through the mountains on its way to Wichita for an important company-wide meeting. 

They can find no place to sit except for two seats right across the aisle from a young woman and her grandmother. After a while, it is obvious that the young woman and Archie are interested in each other, because they are giving each other looks. 

Soon the train passes into a tunnel and it is pitch black. There is a sound of a kiss followed by the sound of a slap. When the train emerges from the tunnel, the four sit there without saying a word. 

The grandmother is thinking to herself, "It was very brash of that young man to kiss my granddaughter, but I'm glad she slapped him."

The project manager is sitting there thinking, "I didn't think young Archie was brave enough to kiss the girl, but I sure wish she hadn't missed him and slapped me!" 

The young woman was sitting and thinking, "I'm glad the guy kissed me, but I wish my grandmother had not slapped him!" 

Meanwhile, Archie sat there with a satisfied smile on his face. He thought to himself, "Life is good. How often does a guy have the chance to kiss a beautiful girl and slap his boss all at the same time!"
