An old guy, a young man, an old woman, and a young women are all riding in a train.

The two women were facing the two guys in the same compartment.

As the train was going crossing the countryside, it enters a tunnel, and everything becomes dark.

While in the tunnel, you hear a k then a Smack.

When the train leaves the tunnel, the young guy is rubbing his face as if he was smacked.

The old lady thinks:

“He must’ve tried to k the young lady and needed up getting smacked.”

The young lady thinks:

“He must’ve tried kiing me and ended up ki !ng the old lady and she smacked him.”

The young guy thinks:

“The old guy must’ve tried to k the old lady and she tried to hit him but hit me by accident.”

The old guy thinks:

“On the next tunnel I am going to k my hand again and Smack the young guy again.”
