Some guys get really upset if you refer to their wife as their girlfriend. I never understood that. It's the same reaction that doctors have when you use 'Mr.' instead of 'Dr.' as their title. "Son, I didn't go to 8 years of medical school to be called 'mister'." My mistake, I thought you went to medical school so that you could go into mountains of debt and get a job healing people. Doctors are the only civilians who get to show off their status in society with a title. Lawyers get to be called 'esquire,' but let's face it, that doesn't really impress anyone.
