There was once a couple who did nothing but bicker with each other. One night, after a particularly big fight, the father accidentally killed his wife. In order to hide the crime he buried her in the backyard and pretended that nothing happened.
The next day their 5-year-old son asked if they could go to a nearby park. The father obliged and played with the child. However, the son kept asking the father why the mother didn’t join them. The father just told him that she was tired.
As they were going home, the father asked his son if he had a great time. The child replied that he had fun, but it would have been better if his mother played with them too. The father repeated that she was too tired.
The son asked, “Oh, is that why you’ve been carrying her on your back all day?”
