What's the etiquette? I suppose since your BP is your nearest and dearest it would only make sense that the parents are invited but what is everyone doing? For example, one of my BM I've been close with for the past 7 years but I've only interacted with her parents when I was in her wedding 2 years ago at wedding activities. For the record, she didn't invite my mom to her wedding but she's never met her either.
