I've only been engaged for two months but I've recently started frequenting theknot.com's forums to get ideas for my wedding next year. But I've pretty much had to stop because I'm so disturbed by all of the negativity/general bitchiness of so many commenters. These should be some of the happiest forums on the internet, we're all engaged/married to our beloved and yet so many feel the need to just tear into others and it's totally unwarranted.
Here are my thoughts based on my observations:
The OP's life/wedding is not your life/wedding. They are a completely different person with completely different life circumstances. They might make different decisions than you would. They might do things that you don't like. That doesn't mean that you should insult them or rudely tell them how to live their life or conduct their affairs. If they asked for advice, be polite and give it!!! If they're totally in the wrong then tell them, but be nice about it. Why would you want to tear someone down months/weeks/days before their wedding? I'm pretty sure you wouldn't want that done to you.
Just my rant for the day. Hoping to find some friendlier forum threads soon.
