Partner and I have been together for many years and have, for all sorts of good reasons, decided to get married next year. Going to be a pagan ceremony, at a beautiful venue, conducted by my oldest and best friend- we're so much looking forward to it. Started telling people in advance- not formal invitations, not yet- just giving people the chance to put it in their diaries. But!- one couple we know have a simply awful child of 7/8. She has no idea how to behave in company, can't keep still- or quiet!- for more than a minute or two at a time, asks loud and inappropriate questions...over and over again, at increasing volume. Her parent think her behaviour is adorable, and assumes everyone else should put up with it. We're hoping the ceremony will be quiet, dignified and will reflect our religious beliefs. If the parents would like to attend the afternoon meal and evening do, that would be fine, but if she ruins the wedding ceremony I'll go ballistic. (Frankly I'd rather she wasn't there at all! But...they've been friends for a long time...) There's good reasons why we've waited so many years to tie the knot, not least that I've been married before and both weddings were cringe-makingly awful, just dreadful. I just can't face having this nasty little brat ruin our day. AIBU?
