Roz Chast’s new memoir.

Calling Roz Chast’s new book a tearjerker would be silly.

The graphic memoir will evoke noises from you that a normal crying person would not make: low moans, ragged breathing.

It took me a second to realize that the Sounds of Grief were coming out of me—I was the person enjoying this fantastically quick-witted, sweet, insanely and perceptively funny new book by her favorite cartoonist. But they were.

Roz Chast’s cartoons have been an (the?) off-the-wall mainstay of The New Yorker for decades. They feature nervously drawn, quavering people, stupidly smiling horses, and inanimate objects with delightful expressions on their faces. They are often set in living rooms and sometimes include a lumpy couch, an armchair, wallpaper, and a really stupid painting of boats on the wall.

On the cover of this book, the author sits with her two aged parents on a lumpy couch that is familiar to us from her cartoons. The argyle-patterned wallpaper is of a deathly hue: dark purple on black. All three of them look deeply uncomfortable.

The title, “Can’t We Talk About Something More Pleasant?” is what Chast’s parents would say to her whenever she tried to talk to them about “end of life plans.”

George and Elizabeth Chast were born in 1912, 10 days apart. They grew up two blocks from each other in East Harlem, and were in the same fifth grade class. Elizabeth had been an assistant principal, domineering and “built like a peasant,” who referred to her terrible temper, chillariously, as “a blast from Chast.” George was a high school teacher. He was slight, kind, an explorer of word origins, a careful chewer of food, and suspiciously inept when it came to using toasters and other gadgets.

He loved bananas; she hated bananas. They argued often about fruit and other things. But they referred to each other—this was both sweet and a little horrifying—as soul mates. They did everything together.

In one of the first pages in the book we read the story of how, one day in 1940, a light bulb burned out in their apartment. George had a phobia of light bulbs and also of step stools, so Elizabeth stood on the stool and replaced the bulb. She was six and a half months pregnant. Soon after that, the pregnancy developed terrible complications, and she gave birth, prematurely, to a “perfectly formed, but blue” baby who died one day after it was born. The complications had nothing to do with the changing of the light bulb, but still the connection between baby death and changing light bulbs became an unspoken part of family lore. The story does not come up again, but it sets the tone of the book, which is a tragedy told in anecdotes.

Baby Roz came along 14 years after that first baby. An only child, she always felt like an intruder in her parents’ “tight little unit.” In the family photographs included in this book, she is not smiling.

In 2001, after avoiding Brooklyn for 10 years, she has a sudden, intense urge to visit her parents, who are nearing 90, in their old home.

The first thing she notices is that everything in the apartment is coated in grime. Her parents are frailer than she thought, and less able to manage. Uneasily, she wonders: what next.

Two days later, the twin towers fall.

Her parents quickly go back to arguing about bananas. But their decline is underway.

In a series of keen, lucid observations of tiny, insane details, Chast describes her father’s senile dementia and her mother’s harrowing digestive ailments, the weirdly cheerful “Place” she convinces them to go live in (she hangs decorative corn cobs on their door, because “when in Rome”), their fear and crankiness, the responsibilities that land on her, the chilling truths about “stuff ” known only to people who have had to clean out their parents’ houses. This is the story of George and Elizabeth’s drawn-out, confusing, stressful, sad, expensive deaths.
