My DH auntie knobhead tried to pull that shit with my wedding my bil and sil got married a few months before but she never mentioned what she was going to wear for their wedding only ours.. and she said she was wearing a white dress.. even mil knew she was being a bitch as this woman does not like me at all. I ingored all her comments and when she could see i wasn't biting she asked me out right if she was allowed to wear white i said no i told her i thought it was rude and not very classy.
She made a dig about it to my face at bils wedding after one too many drinks i just ignored it and carried on being pleasent no way was i going to spoil my bil and sil big day!
She didnt wear white to my wedding i cant even remeber what she wore but her and uncle knobhead acted... well like knobheads at my wedding.. she cried the whole way through the ceremony and meal. Loudly but made a point of telling everyone she wasnt crying because the wedding was nice or the ceremony was at all moving. She balled her eyes out during my husbands speech and started an argument with her husband that he never said anything like that to her on their wedding day.. he replied with "he wouldn't of meant any of those things its just what you have to say at weddings" utter cock 
Uncle knobhead clicked his fingers at our serving staff. Shouted at my auntie to pass the potatoes.
UK also insulted my dad and basically called him a lazy scounger my dad is a full time carer for my disabled brother my bil has severe autism and learning difficulties. I thought my DH was going to punch him through a window there and then he loves my dad.
UK Showed me up on the dancefloor he grabbed me straight after my first dance and threw me round the dancefloor. Theres a video of that somwhere.
They both made a point of dancing with as many people to opposite sex to make each other jealous which ended in hysterics from AK
UK Then picked on an autisic family member from DH side and provoked the lad to scream at him that he was nothing but a c*.
Also he coughed loudly and cleared his throat in a exaggerated way throughout our ceremony, the speeches and the cake cutting.
We will never invite them again to anything.. ever.
And breathe! Sorry i got carried away needed to get it off my chest.
