Yesterday I learned a guest planned her wedding the same day and time as ours. She is a family friend to both of our families and I've told her multiple times this past month our wedding date and she will be getting the invite after the New Years. She got engaged herself less than 2wks ago. This wouldn't be such a big deal (besides hurt feelings) except 1-small town so everyone-knows-all. 2- a good chunk of our guest list will be included on hers. Advice on what to do without being snarky?
