Carefully read these two sentences:
“Finally, Eddie, our building super, delivered the worst line of all: And you shall fail to save what matters most, in the end.”
Finally, Eddie, our building super, delivered the worst line of all: And you shall be unsuccessful in saving what matters most, in the end.
The words in bold have very similar meanings.
Why does the author choose to use the word fail? How does this affect our understanding of the first sentence?
