My boyfriend's name comes up KEITHA. Also, my full first name is almost identical to his last name, which sometimes confuses people. (If you are wondering why similarities between my first name and his last name would confused people, join the club.)
Once I called in to make changes to one of our reservations and the agent referred to him as my "wife". I did not care, so I let it slide. Eventually, I think the agent noticed that our last names were actually different and that his first name was probably Keith, as she stopped calling him my wife and started to refer to him by his name.
