I would tear apart heaven and earth to find her again

I think a person would like, look at it everyday, or mark the date it is supposed to go to zero.

That's why in the movie you have sound signal when you reach 00:00, if I remember correctly...

OH MY GOD NOO NOOO STOP THE TRAIN

Isn't this the premise to Timer?

This person needs to write a book

What if you met them and they left, does it restart.

You know there was a movie made where this was the premise. They had a simple alarm built in so that when you reached 0:00 you'd know.

What if you fell in love with someone but your clock kept counting down? How horrible would that make you feel

What if your timer just stopped before it hit zero?

What if u locked yourself up at home with the windows shut and stuff

I'm sitting at home doing nothing special, just talking to people on a server. Then someone logged in when my alarm simultaneously rings. "Did your alarm go off too" i say, they reply saying "yes it did, i guess your my soulmate?". "I guess so, knew it'd be my luck to have it happen while playing a game :p" I say, with my heart jumping into my throat. Then it all crashed down onto me, how long will it be until I'm even able to see them via webcam. And what about in real life? Am i doomed to be in love with someone being unable to hold them?

we went over this 13 weeks ago guys...

What if you met your soul mate before you got that timer? It wouldn't be very useful then
