I invited a group of distant school friends to my wedding, usually they’d be evening guests but we’re having a twilight wedding and having the same people from beginning to end. One of my best friends also went to school with me and is good friends with them. All but one let me know they can’t make it for various reasons, and the one im least friendly with hadn’t even rsvp’d but when I chased her up she said she’ll almost definitely be there. I don’t want her sitting with my best friends (especially since she’s sounding flakey) but now none of her close friends are coming so AIBU for sitting her on a table of my work colleagues and some couples?
