Healthy marriage = mutual fear of consequences, apparently

A married couple claimed they never argued in their 25 years of marriage.
A friend asked, "How is that even possible?"
The husband explained, "It all started during our honeymoon when we went to a ranch. While horseback riding, my wife’s horse suddenly bucked, and she fell off. She calmly got up, patted the horse, and said, 'That’s your first time.'
A little later, the horse bucked her off again. She stood up, patted it again, and said, 'That’s your second time.'
But when it happened a third time, she pulled out a gun and shot the horse.
I was shocked and yelled, 'Are you out of your mind? You just killed the horse!'
She turned to me with a calm look and said, 'That’s your first time.'
And from that day on, we never had a fight."
