“Do NOT bring children to a child-free wedding — no exceptions. Do not ask for an exception. If you can’t get a sitter, don’t go. Not comfortable leaving your kids with a sitter? Don’t go. There are plenty of places you can’t bring kids: bars, clubs, jobs, etc. No one would try to bring their kid to a nightclub, so don’t bring them to a wedding.”

As a Senior Staff Writer at BuzzFeed, I cover real-life stories that explore relationships, lifestyle (including travel and beauty), and the internet's most fascinating trends.

"I registered for a $6 box of coasters because I actually wanted, and would have used, those coasters. I did not register for a (probably over $200) solid silver salad bowl, designed to look like woven bamboo, because I do not want it and will never use it. Because it is engraved with our last name, no one will ever use it. It was a waste of money and the materials needed to make it. Save your money, save the planet, and get things the couple tell you they need/want rather than things you want them to have.

*If the couple registers for insanely expensive gifts like a new couch, all bets are off."

"People just don’t understand wedding etiquette anymore. It’s awful."

"All of this only happened because she finally, after months of me asking her to, drove the 70 miles to my city, where I drove us around to shop for her MOH dress. She caused me to be called a bridezilla countless times and caused more tears and stress than any other part of my wedding planning. I wish I had said screw it and asked her to just be a guest and not stand beside me."

"Don't RSVP 'yes' and then not show up. I don't mean because you got sick. We had someone tell us a few days in advance that they thought they could fly up, but turned out they couldn't. Or it was 'too hot.' One couple just no-showed, and we found out later they were at another party. Cost us $150 per person and messed up our seating arrangements."

"My husband’s sister-in-law made a request for the DJ to play her and her husband’s 'song' and announce their anniversary (which was actually two weeks earlier) and got their own dance. All without ever even asking the happy couple if they minded. Horrible people. 😡"

"Have an empty glass or trash? Hold on to it until you can properly dispose of it, and that doesn’t mean the floor :)."

"Five years later, and I’m still butthurt. Lol."

"My extended family on my mom's side still aren't speaking five years after my wedding because my cousins were so hurt that their three young kids weren't invited to my wedding. I made it clear from the jump that no one under 21 was invited. It caused a huge fight and rift in my family. THE DAY IS ABOUT THE BRIDE AND GROOM, NOT YOUR CHILDREN."

"I once had a guest complain at my wedding that the bar service was 'slow,' and all it did was stress me out because a) I didn’t have control over the bar service, and b) my husband and I had paid for a completely open bar, and I hoped it’d be enough to keep people happy."

"I'm still not clear on why he thought I would be impressed that he was stealing booze at my wedding."
