I agree with others who have said that years ago, we managed without any of this rubbish, yet nowadays, when they have lived together, got a home and possessions, and probably children as well, they want these big, flashy, over-the-top hen parties, plus extravagant wedding to boot.
If Covid and Lockdowns have left us with any pointers for the future, scaled down weddings and hen/stag parties would be a good start.
You don’t need a big, flashy ‘do’ with the world and his wife in attendance to make it all official.
