We often regret something we did in the past. A decision we rushed into without being fully aware of the facts or the consequences of our behaviour. An action that with the glorious benefit of hindsight we might well have abstained from altogether. These are the things that once done cannot be undone. Or can they? Before you get too excited, Aston most definitely isn't returning to Strictly.
If reports are to be believed, some of the fabled 52% are starting to rue the day back in June last year when they decided it would be a good idea if we left the EU and once more made our own way in the world; free to again travel the globe in search of wealth and prestige like our seafaring forebears.
What few people didn't apparently consider was the prospect of our esteemed nation crashing out of Europe in spectacularly tragic fashion with no deal to speak of, thereby leaving us humiliated and our initial bravado looking ever so slightly misplaced.
Increasingly, Brexit is being touted as a blunder. The fault of the gullible working class who were spoon-fed a lot of spurious information, only to swallow it whole. A day hardly passes without the doom-mongers warning of the choppy waters ahead.
Just last week the Bank of England were bemoaning the estimation that 75,000 jobs could disappear in the financial sector. But they say this as if it were a bad thing. A cataclysmic by-product of a referendum they and their ilk never wanted to take place to begin with.
Yet to a great many who voted out and still want out, isn't the prospect of highly paid, bonus-incentivised bankers either being left without a job or having to relocate to Frankfurt, a cause for celebration rather than commiseration?
You can bet that these Leavers aren't having sleepless nights or crying into their soup, frequently being sourced along with other foodstuffs from foodbanks, over the fates of those who they see as helping to bang the final nails into the coffin of Britain's great manufacturing past and subsequently turning the entire country into nothing more than one giant service centre staffed by people on low wage zero-hours contracts.
On the contrary, they're rubbing their hands together at one of the first genuinely decent pieces of Brexit news they've had. Now if only 100,000 estate agents could be relocated to Bratislava, they'd probably be cock-a-hoop
Unfortunately, for the middle class (the political, social and cultural elite) such news isn't nearly as welcome. Particularly if the absolute worst happens and EU nationals suddenly find it far trickier to work here than it once was.
This could mean that British bosses find themselves in the unenviable position of having to recruit homegrown talent. Heaven only knows what that will do to the price of a Pret A Manager salad and a packet of Kale crisps. For God's sake, tens of thousands of us may soon be forced to regularly visit a Subway or a Greggs. I mean, imagine the carbs.
Then there's the knock-on effect of more expensive plumbers, cleaners, gardeners and childcare professionals. Damn! And just when half of Islington parents and their offspring had finally mastered the nuances of Romanian so that they could confidentally converse with the nanny.
All, however, may not be lost for the Remainers out there. According to Lord Kerr who drew up the original Article 50 legislation, we could unilaterally reverse Brexit. This is despite Theresa May firmly stating that there categorically is no way back, which knowing her almost certainly means we're having another referendum next Thursday.
Kerr's assertion is unsurprisingly echoed and endorsed by a host of figures from Gordon Brown and Vince Cable to Angela Merkel and last, but not least, Donald Tusk.
As President of the European Council, he simply can't wait to welcome us back into the family. Although in his case, one suspects it's akin to Michael Corleone forgiving Fredo. And we all know what happened to Fredo.
No matter what anyone says, there's no conceivable way we could, would or should stay in the European Union.
Brexit wasn't a sweater we could return to M&S and as long as we kept the receipt, all would be fine. It was a seismic shift in the politics of this country, decided upon by a majority of the electorate. To reverse it would be to admit that we are no longer a democracy.
Whatever happens along the way and whatever the eventual outcome, we've made our bed and we must lie in it. We can only hope that when new trade agreements are forged, the Americans and the Chinese don't snatch too much of the duvet.
