I want to shake FI! We were talking with my grandma and it came up that apparently a wedding I attended when I was 14 was a PPD. The bride had a destination wedding which my grandparents attended and a beautiful second "wedding" at home.
As soon as I heard I started bad mouthing it and pointed out FI was invited to a PPD next year. Both FI and grandma thought it was fine so I read word for word the PPD FAQ and both of them laughed said me and this site were silly and if people want a "real" wedding who are we to stop them.
