When you are preparing your wedding, it’s nice to know exactly how many people will show up, because a lot of your expenses and plans depend on the guest count. That’s why a guest must let the couple know whether they will attend, and why many invitations contain a card to make that easy. But brides would also like to know what kind of nightmares you're going to bring with you. Bob Powers posted this modern version of the wedding RSVP card at Someecards. It contains the most common obnoxious behavior among wedding guests, and it should have a second page for warnings of any disasters not specified on the first page. -via Laughing Squid
I used to work in the bridal industry and I saw a lot of this "it's my big day, no one else has a right to have fun/cause drama/take attention away from me" attitude.
