Life is all about choices...

Two stories start to develop after a stupid coin-flipping action on the brooklyn bridge. I am not a big fan of this kind of choice making process. Perhaps it is fair enough to let god be the judge, but isn't it a little bit spontaneous and irresponsible?
Anyway, both stories are about making choices and are characterized with colors, yellow and green.
I could not help but wonder if it is to demonstrate that this is a typical American movie by using these two colors that are missing on the US flag?
No matter they are involved in a dangerous situation chasing by criminals, or they are just enjoying the family hours besides a barbeque grill. Life is all about choices. Some are tiny, some are significant, some are relevant to whether you could carry on a living, some are relevant to whether you could bring more times of bitter-sweets up into a family. In the movie, they did the right thing finally. But it dosen't cost nothing. Some have lost 500,000 dollars, some have lost a whole life time with no diapers. In return,one could not gain anything without losing something. Does not the serenity worth more than that?
What I am uncertain of is how many choices are out there waiting for them, but what I am certain of is that they will live happily ever after...
