They seem to be the perfect example of how to take a typically, very traditional and nerve wracking occasion and make the choice that it would be a day about what is important to them; simply being surrounded by their closest friends and family. Most importantly though they chose to be themselves; happy go lucky with nothing to prove to anyone!
Maybe it was because they already have a beautiful, established family that symbolises a bond that will last forever? Maybe it’s just that people who live by the ocean are a bit more chilled? But I suspect it’s because they don’t have doubt in the world who they want to spend the rest of their lives with. They’d already made that choice!
