There’s a reason people usually marry someone of own background/class. If there’s a gulf it can be problematic. I remember ‘Alex & Sue’ who met on Blind Date, working class Sue meets Upper Middle class, Alex. Her family warm & confident & his, slightly aloof. Alex himself slightly bonkers but great guy. It worked & Sue ‘became’ upper, middle class.
I’ve also been to a similar wedding as above. There was a lot of ‘they’re up themselves’ from the Bride’s (working class) family & mutterings of ‘she looks like a tart’ from the other, upper middle. The upper middles were old money but couldn’t afford enough booze for do - the bride’s fam suggested a pay bar. Fall out…So, us guests had to arrange an emergency run to Threshers. The posh lot nicked the best wine for top table.
The bride’s fam also wanted the uncle, a pub singer, to do a medley of songs at the stately home. They banned him & he was seething & so on. Groom’s fam men all owned tails/morning suits, Bride’s went to Moss Bros…
If there had been social media at time likely worse. Mum’s fam wanted a knee’s up for engagement & a stripper…Not so other side.
It was hilarious, rather sad & marriage didn’t last.
