What if you'd never seen a thunderstorm before? The world suddenly darkening, the wind blasting you in the face, the sky rumbling over head as black, ominous clouds blocked out the sun... what would you think? That the world was ending?
What about a sunset? If you didn't know that light would come back? If you watched it creep back towards the horizon and disappear leaving you in utter darkness. Wouldn't you abandon all hope?
What if you didn't know there was a tomorrow? If this day- today- was suddenly all you had? And you spent it as you did- paying bills, working at a soul-sucking job, doing dishes, laundry, mowing the lawn, cleaning your bathroom... how cheated would you feel?
See, that's the problem with Carpé Diem. It goes in direct contradiction to what we have to do in order to survive. In direct contradiction to responsible (and often dull, stressful and completely un-enjoyable) living. And yet, that's what we wish we could all do.
All I know is, if today were suddenly the last day of my life- I'd be pissed.
