In 1991, I agreed to Mrs Duke accompanying me on a business trip to, of all places, Waco, TX. I warned her the testing we would be doing would be going on both day and night, and therefore I would be very busy the entire week. Since she had a friend who lived there, she said that was OK since she could pal around with her while I worked.
I'll skip the details other than to say between test failures that kept me busy 15-16 hours a day and her friend not being available as much as had been anticipated, Mrs Duke spent a miserable week in July in Waco with nothing to do except hang out with a couple hundred older amateur bowlers at a very dated Holiday Inn. And make no mistake, she was not shy about telling me every evening that week just how miserable she was.
I learned a valuable lesson, and refused to take her on any further business trips I went on the rest of my career.
