So, I won't really go into details, but I have a (really close) friend who is now engaged and is discussing doing some big etiquette no-nos with her wedding. I feel like she's on the road to both being disappointed when things don't go how she expects, and to insulting a very extensive guestlist. I don't want to stand by while she digs herself a hole, but I don't know how to approach these subjects without insulting her, or to say my opinion if she brings these things up. I would appreciate any suggestions on how to do it, or else you guys should just hold up a big stop-sign, and I'll try to bite my tongue over the next year.
