You are standing on a platform at a train or subway station. As the train approaches you are thinking:
A) Someone could easily push me off the platform into the path of the train. What if someone pushes me?
B) I could push this guy/lady right now. They wouldn’t even see it coming.
C) I could just jump right now off the platform into that train. Just like that and it would be over.
D) There is my train. I will get on when it stops and go where I am going.

My experience is that most people are pretty consistent about their platform thoughts and rarely waver. I imagine that most people consider choice B many times while waiting for trains. I find it pretty tough to convert from choice C to choice A. Of course, D is never an option of train-thoughts.
