... Inspired by a thread in AIBU. (But not a thread about a thread. )
what is the worst behaviour you have seen/witnessed/heard of at a wedding?
A couple I have heard of.... Groom's mother turns up dressed in her own wedding dress and carrying a bouquet.
Another one.... during wedding speeches, Grooms mother gets up and welcomes her DIL into the family by stating 'Remeber. He will never love you as much as he loves me'.
