That’s Not How You Pronounce Your Name
It’s not uncommon for people to refer to others by their last name. We see it all the time in professional sports and in the Harry Potter books, where the Hogwarts students called their enemies by their last names. This woman’s co-worker meant no harm, but man, was he annoying.
When he learned her last name, he asked her for her origin, after which he went into excruciating detail for ten long minutes concerning how she was mispronouncing her own name wrong. Seriously, who are you to tell people how their names are pronounced? Should we call you D-Bag or d’Bag?
