Before getting married
Karen Mobley's mother had this advice.
"If you think you want to marry him, go on a long car trip requiring extensive use of maps and return home to do a complex home repair. If you still like each other, then try it."
GPS systems might have reduced the volatility of part of that scenario. But I'm not aware of any technology that has defused the incendiary possibilities of couples taking on home remodeling.
