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 for that young man to kiss my granddaughter, but I'm glad she slapped him."
The Project manager is sitting there thinking: "I didn't know the young tech was brave enough to kiss the girl, but I sure wish she hadn't missed him when she 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!"
The young programmer 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 Project manager all at the same time!"
