An amusing family story is of my grandparents (on my fathers side) did the vows part and went separately to the venue for the evening doo
Grandad walked in,found his wedding party,got stuck into the food and champagne with gusto,chatted to the guests and didn't really give his bride a thought
After about an hour,the penny slowly started to drop that he hadn't seen her at all
Then it dropped a bit further that he'd been chatting away to total strangers
He'd got the wrong floor and wrong wedding party!
He slunk out,finally found the right floor,grovelled a bit to his new bride and started all over again
I did ask what granny thought (I couldn't ask her as she'd died before I was born) and apparently she wasn't that surprised and knew he'd surface at some point
Best part is,years later,he did exactly the same thing at my mother's 21st birthday party!
It runs in the bloody family,his son,my father is exactly the same-my mother had to keep an iron grip on him on their wedding day and I once went to the wrong funeral (was meant to go into one room at the crematorium but ended up in another and was halfway through a strangers funeral before I noticed!)
