Wedding season is officially here and, sadly, it can sometimes bring out the worst in a person. You've heard the horror stories - the mother-in-law who loudly declared, mid-ceremony, that a marriage between her son and "what's her name" would never last; the uncle-slash-photographer who not only got so drunk that he fell through a wall, but also failed to load his camera properly so that the bride and groom were left without photos; the woman who live-blogged how much she hated her friend's wedding, from the "alright" food to the "tacky" bridal car.

Luckily your friends and family would never act like that, right?

While you hope that your loved ones will behave like grownups, there's always the possibility that someone could cause a scene that's talked about for years to come. To spare them the embarrassment (and many unflattering Facebook photos), we turned to wedding planner Cynthia Martyn for tips on navigating tricky guest-related scenarios with your friendships firmly intact.
