The train goes into a dark tunnel and a few seconds later there is the sound of a loud slap.
When the train emerges from the tunnel, the Kiwi has a bright red hand print on his cheek.
No one speaks.
The old lady thinks:
The Kiwi guy must have groped the blonde in the dark, and she slapped his cheek.
The blonde Swiss girl thinks:
That Kiwi guy must have tried to grope me in the dark, but missed and fondled the old lady and she slapped his cheek.
The Kiwi thinks:
The Australian bloke must have groped the blonde in the dark. She tried to slap him but missed and got me instead.
The Australian thinks:
I can’t wait for another tunnel, just so I can smack the Kiwi again.
