“Hemingway uses nature as a foreshadowing of things to come.
Take rain for example in A Farewell to Arms. For Hemingway,
rain is often indicative of rebirth or death, occasionally a mixture
of both. It could also be representative of transition and change.
It can bring replenishment and nurture life, but in large amounts,
in over excess, it can bring suffocation and death.” – Josh Silverstein
