I saw it too a couple times... But it was someone who did it intentionally to piss off the bride, and don't worry in all cases she took a lot of heat over it... One of them left crying, the other accidentally had red wine spilt on her.

Don't send them home... Just revel in the treatment they will get from your friends and family all night and enjoy your own night for what it is... Your night.

They may be wearing a white dress, but you're the one wearing *the* white dress.
