Here’s a fictional one that I wrote for your enjoyment:
My wife and I have had a happy marriage. We have what many would call an…unusual…arrangement that started 9 years ago that we keep secret from my identical twin brother.
First of all, let’s be clear. My brother is a jerk. He’s a high-stakes business man that owns several companies and was making millions before he turned 27. He’s also selfish, rude, and conceited. He’s never had a successful, long-term relationship because he treats his girlfriends so poorly.
I, on the other hand, have always tried to be kind and gentle toward others. My wife and I met while I was in a master’s program. She was and still is the best wife a man could hope for. We married once we graduated.
After we got married, my twin brother felt he needed a wife also. But, like the weirdo that he is, he hired a matchmaking service that paired him with women from Latvia in eastern Europe. We were shocked when, after visiting Latvia for only 3 weeks, he came home with a fiance and announced that they would be married in just 3 months.
