My name has been mispronounced since I started college. It drives me mad. And people still get it wrong after I tell them. *insert expletive*
I usually went the opposite way with the name mispronunciations. My classmates usually got annoyed on my behalf while I tended to laugh because its happened my whole life. I also kind of enjoy hearing the different ways people decide to pronounce my name (most of which make absolutely no sense).
