A young man, about to wed, asked his grandfather to the secret of his long, happy marriage.
The grandfather said, “It’s pretty simple really. My wife and I made an agreement on our wedding night that I’d make all the big important decisions and she would make the decisions on all the little things.”
The grandson asked, “How did that work?”
The grandfather replied, “Nothing important ever came up.”
(Apparently that is an old Bosnian joke.)
