Train driver and the passenger

Just now when i was taking a train to somerset, I suddenly tawt of some scenarios that may happen in life...

Scenario 1
I was rushing for time then I saw the door of a packed train closing on me when I was walking up the escalator. Felt sad but two minutes later an empty train came along and I just wasted two minutes to enjoy 20 minutes of comfortable train ride.
Moral of the story: Do not be despair when a door closes upon you, cause you do not know what good things will befall on you next.

Scenario 2
A passenger is waiting for a train driven by the train driver whom he knows for a long period of time and allowing other trains to go pass him without boarding. Either he will successfully board the train of that driver or he will just carry on waiting there.
Moral of the story: Some people are just dumb to wait for that particular train when he can just board other trains instead.

Scenario 3
The train driver can only picks up a passenger out of all the people at the train station, how is she going to choose that person. She can either wait for the right person to appear or just allow the person whom she thinks is the most suitable to board first.
Moral of the story: The train driver will have the luxury to choose which passenger she thinks is the right one to board the train.

To conclude, life is about choice, every single decision that you make will affect your future.
