Just read this great article on The Knot "The New Rules of Wedding Etiquette" - so, how exactly do we ask our guests to put away their phones or not to post pictures or comments from our big day before we do? I have one girlfriend who is particularly rude with her phone at every social occasion and when asked to put it away, she always makes a loud stink. I would love to avoid that on our wedding day, and having her (and others) completely present would be a joy. Advice anyone?
