DEAR MISS MANNERS: My mother-in-law and sister-in-law wore white gowns to my wedding. Their actions were so obvious that guests commented on it, and the DJ asked for “the real bride to please stand up.”

Why would they do this on my wedding day?

GENTLE READER: A mean-spirited prank gone wrong? Regardless, it does not bode well for your future relationship with them. Or for a shared sense of humor.
