When I hear someone say "I hope that doesn't happen" I immediately think there is an exit strategy. 
It's way another way of saying "I'm choosing not to deal with that situation at this time. Maybe it will just go away."
I talked about this idea of doubt and fear being paralyzing yesterday. Hope is an avoidance strategy giving oxygen to doubt and fear. 
Whenever I catch myself saying "I hope..." I ask myself:
What can I do about it right now? 
You see challenging situations just don't go away with avoidance. They collect interest at your expense.
Taking action for the outcome you want is a strategy, hope is not. 
Even if you take action and fail you have gained a learning opportunity to grow and improve. 
Hope gives you nothing. 
Get after it!
