How many people have you just 'known' were going to marry the wrong man or woman? But did you take them aside before their big day and quietly ask if they were 'sure' they were marrying the right person? Girl-to-girl, this is code for "You must be NUTS marrying this guy. He's a cheating, unreliable jerk." Or man-to-man, did you simply tell him point-blank "This woman is BAD news. Don't marry her. She will wreck your life."
