The tern second

I'm on vacation in Las Vegas. That doesn't really mean the same thing to everyone who reads this. I'll write something short, that I was made to think from... a movie.
Imagine this moment:

... You're on the street and find you're short of a dollar to getting something you really need (supposedly). Of the few people around someone looks dressed like he has money. And you ask him for a buck... but he was even poorer than you, he was... POOR. He gives you the dollar without saying anything, even though he might not eat that day...
The tern second that this happens the world turns around. Values... fate, decisions... what are they?
