A young man was considering asking his girlfriend to marry him. His grandfather and grandmother had been married for 70 years, so he asked his grandfather for advice.
His grandfather said that he had one very important piece of advice for a long marriage. "When we had been married for 5 years, we went horseback riding one weekend. As we were getting back from the ride and closer to the barn, the horse threw your grandma and she landed pretty hard. She got up and grabbed the horse by the bridal and said 'That's One'."
"She remounted and we kept riding toward the barn and the horse got skittish again and threw your grandma again. Grandma got up and grabbed the the horse by the bridal harder and said 'That's Two'."
"She remounted again and we got almost to the barn and the horse threw her again. Grandma got pretty upset, went to the truck and grabbed our shotgun and shot the horse."
"I said 'You just shot that horse!" Your grandma looked me in the eye and said 'That's One'."
We've been happily married ever since.
