Dont believe anything

I heard this story many years ago in a mining village in the north west province and i told it to some of my friends.......
It is known that miners work long hours underground  and that they sometimes work a lot off overtime.As we went down the shaft one day ,which was one of the deepest mines anyway 3km down., i  was approached by one of the guys and he had a story for me.
A miner was told that his wive had a affair and when he was on night shift she would slip out of the house and meet her lover somewhere else.Week after week  his mates told him that story. He decided to check this out and went back to his house one night and waited outside .Then she  came out ran in the dark to another house opened the door and went inside.At this time the miner was so furious   grabbed his sambok and stormed into the house opened the bedroom door and gave his wive the beating of her life.
The miner went back to work and went home after his shift like nothing happened.His wive was still sleeping when he arrived and tip toed to he kitchen  .Next moment the wive walked past him  without a scratch on her!!
Don't believe anything you are told.!!
