My fiancé and I are getting married in August, and his mother “Agnes” is insisting that I wear her wedding dress. I have a sense it’s because her only daughter refused to wear it when she got married two years ago. After having seen the thing, I can appreciate why: It’s hideous. I already purchased a dress that I love over a month ago, but Agnes won’t take no for an answer. My fiancé says the thing to do is ignore her. Easy for him to say since he’s not the one being endlessly needled! Can you suggest a way to tell Agnes it’s time for her to shut the fuck up?
