What internal conflict does Tom's external conflict cause in "Contents of the Dead Man's Pocket"?What event introduces a new obstacle in Tom's...

To me, the external conflict is between Tom and the building.  It is between Tom and death.  He is out there on the ledge, fighting against death.

This causes an internal conflict.  It causes him to start thinking about what is really important in his life.  He comes to question whether he is spending too much time and emotional energy on his work.  He has to decide whether his work is more important than his personal life.

I think the new obstacle you are talking about is when the paper flies out the window.  Now he has to do it all over again.
