It takes two to conquer a situation. Of the two it only takes one to destroy a successful outcome.
The story is told of a man who fell into a well. He called out for help and someone heard him. When his help came to his rescue, he threw him a rope and said I will pull you up. The man then started to complain that the rope was not strong enough to help him. He explained to the helper that it was not made of the right material. The helper tried everything he could to help the man but he found an explanation on why it would not work. Eventually his helper walked away and came back with a truck filled with sand and started pouring it down the well. The man eventually died.
Moral of the Story
It takes two to get to a solution. One can throw the rope but the other needs to hold the rope to get out.
