My Mum forgot to bring my wedding dress from her house to my Brother's where we were all getting changed.
I'd hidden it there so my husband didn't see it. Made my Mum and Dad fully aware of where it was and what to bring. REALLY made my Mum aware as she's the sensible one and Dad forgets things when he's stressed.
Anyway, makeup and hair done, on schedule no less! I go to get changed and big white bag full of the dress is nowhere in sight! She'd brought, her outfit, my dad's my BILs suit, my DSs dress, coat and SPARE COAT. But not my dress!
Whilst she had a full meltdown blaming everyone, I booked a taxi for my DB sent him to their house (40 mins away) and got to ringing the the registry office and party venue to see if we could delay. All the while telling a crazed mum to STFU, as she yelled some more, I have to fix this now.
A vodka later my DM and DD were sent to think about their actions in another room, DS and BIL sent to the registry office to handle it there.
I was fully prepared to call my DB back and get married in jeans and a t-shirt.
Apparently, my MIL asked my DH if he thought I was having second thoughts as no Mother would do this to their child....he laughed and said "no, this is the shit that goes down in their family". He wasn't wrong!
This was not the end of the events of my wedding day....but then you only asked about mothers!
