From the article, 15 Things Kurt Vonnegut Said Better than Anyone Else Ever Has or Will:
13. “So it goes.”
Unlike many of these quotes, the repeated refrain from Vonnegut’s classic Slaughterhouse-Five isn’t notable for its unique wording so much as for how much emotion—and dismissal of emotion—it packs into three simple, world-weary words that simultaneously accept and dismiss everything. There’s a reason this quote graced practically every elegy written for Vonnegut over the past two weeks (yes, including ours): It neatly encompasses a whole way of life. More crudely put: “Shit happens, and it’s awful, but it’s also okay. We deal with it because we have to.”
This sums up exactly what I believe about the quote, so it must be true.
