I'm going to answer this in the style of a story so here it goes:

Not much sleep last night but hey why does it matter.
The shocking news still has not set in. i mean how can you sleep if you know that the world is going to end by the end of the next day.
I draw open the curtains to see the sun just kissing the horizon as it raises for the last time and invite my wife and children to witness the beauty of it one last time. theirs a peaceful silence between us as the sun lights up our cheeks and we just look at each other with tears of love.
when day light breaks i turn to my wife and children and ask what do you want to do with your last 24hrs.
my wife says "visit all that mean a lot to me and say thank you to all that have taken there time to contribute to our lifes". I give her a hug letting her know that how great she is.
my daughter, who is 7 says " i want to spend all of our money on treats" and with a big smile i hand her our savings and away she goes. I mean what is a 7 year old to do really.
my son of 13 reply's" I want to do everything i have not been aloud to do in one day like taste alcohol or drive the car or even both" i just laugh and agree but tell him "as long as you are here with us when the sun sets do what you like."
Several hours pass by and i hear my family returning . thay find me still staring out of the same window where they left me that morning and my wife holds my hand and says " what about you, what did you do with your last day?" i pull my family in close and with a big embrace i reply
" All i want out of life has been achieved, as long as you all are happy and have got out of life what you wished for then my life is complete."
With that we turn to the window as the sun sets for the last time.
