Loving this thread but feel bad for those of you who have had real nightmares Few stories of innapropiateness from mine but let me qualify this by saying that I had a wonderful wedding day and none of the following had any impact on mine or 99% of the other guests enjoyment, who tell me it was a lovely day (hope they are not just being polite!) :-
Black sheep SIL (who my DH didnt really get on with) was invited with her 3 children and the father of her youngest daughter. She replied she had just finished with him so could she bring 'a mate' To which both myself and DH replied no, (we didn't want some random at our wedding and as you can imagine that place was wanted for someone we actually knew and cared about!) On the day, she just didn't show up! MIL hadn't heard from her for a few days so didn't know anything. 3 days later we heard via MIL that she 'forgot' then she said even later that her Ex had been trying to take the older boys into care and it was all she could deal with. I still don't know to this day what the actual story is and if its true then I sympathize but I do feel that she could have called or even asked someone else to let us know. Unfortunately she has recently gone totally off the rails, but thats another story.
So that left half an empty table, the other guests on that table were DHs v elderly nan, MIL's BF, plus her daughter and MIL's younger half sister, who turned up in a rather inappropriate short and skin tight leopard print lycra dress. BF and daughter were tee total, so AIL proceed to drink the lions share of the 4 bottles of wine allocated to the table, make a bit of a tit of herself trying to chat up our male friends and told us 'it was the best wedding she'd ever been to' I bet it was Pretty harmless really, it didn't really bother me but poor DH was a bit embarrassed (now i know why he refused to invite any of his cousins)
At the end of the night, apparently MIL and FIL had a punch up in the car park, as MIL's BF had been shit stirring between them, Again don't know the whole story as wonderful Best man and his wife, my Best girl, sorted them out and kept them away from myself and DH and calmed the whole situation down.
After the reception, we went back to the hotel where we were staying with my family. We sat in the bar having a quiet night cap with my folks and my Sis and BIL. Quite a few of the other guests where staying there and the very drunk (and i am sure coked up) brother of my best friend spotted us and came over to buy us a drink. Unfortunately, he was being very obnoxious to my lovely BIL, saying he didnt deserve my sis and she should come up to his hotel room instead. He then proceeded to order 2 bottles of very expensive champagne just to piss off the snooty waiter (which we didnt complain about ) but it was all a bit embarrassing and uncomfortable so we soon called it a night. He THEN proceeded to follow us up to the honeymoon suite and try to get in the room saying we should keep on partying. I kind of lost my SOH at this point and slammed the door in his face. I found out later that the hotel then refused to let him check into his room as he was so obviously hammered and my BF had to get a cab all the way across town where she was staying with friends to collect him
