If the world were ending in 24 hours... I guess my answer depends on how exactly the world would be ending. :)
Is a meteor coming for us? Is it nuclear armageddon? Was a plague unleashed? A supervolcano erupting?
In this context, I will assume a meteor of gigantic proportions. And my honest answer is - I would grab my partner, we would spend the day partaking in whisky, and by the time it lights up our skies and signals our doom, we would simply welcome the end. Not much else one can do. ;) Be at peace.
mmm i was just imagining like...the lights turn off like in a teather, and it's over! not catastrophic meteorits, no nothing, just emptiness! thanks for your reply ;)
