One woman decided that partying was far more important than supporting her sober friend, claiming the ‘wedding was boring’ and then rallying a troupe of other party animals to ditch the wedding early to go out to the bars.

Nobody knows how to ruin a wedding celebration quite like a Monster-in-law.

Sisterly loyalties only go so far, and when one woman's sister, the bride, thought she'd play god with her own sibling's relationship, things backfired. Frankly, weddings bring out the cringe in all of us. Whether you're a sorry sap that cries during the vows (guilty as charged), the distant aunt who reminds the bride that they used to change their diapers, or you're the guest that drinks too much at the open bar, there's some social mixing that brings out the worst in everyone.
