In May, 1970, a few nights after the Kent State shootings, my father and my brother Tom, who was nineteen, started fighting. They weren’t fighting about the Vietnam War, which both of them opposed. The fight was probably about a lot of different things at once. But the immediate issue was Tom’s summer job. He was a good artist, with a meticulous nature, and my father had encouraged him (you could even say forced him) to choose a college from a short list of schools with strong programs in architecture. Tom had deliberately chosen the most distant of these schools, Rice University, and he had just returned from his second year in Houston, where his adventures in late-sixties youth culture were pushing him toward majoring in film studies, not architecture. My father, however, had found him a plum summer job with Sverdrup & Parcel, the big engineering firm in St. Louis, whose senior partner, General Leif Sverdrup, had been a United States Army Corps of Engineers hero in the Philippines. It couldn’t have been easy for my father, who was shy and morbidly principled, to pull the requisite strings at Sverdrup. But the office gestalt was hawkish and buzz-cut and generally inimical to bell-bottomed, lefty film-studies majors; and Tom didn’t want to be there.

Up in the bedroom that he and I shared, the windows were open and the air had the stuffy wooden-house smell that came out every spring. I preferred the make-believe no-smell of air-conditioning, but my mother, whose subjective experience of temperature was notably consistent with low gas and electric bills, claimed to be a devotee of “fresh air,” and the windows often stayed open until Memorial Day.

On my night table was the “Peanuts Treasury,” a large, thick hardcover compilation of daily and Sunday funnies by Charles M. Schulz. My mother had given it to me the previous Christmas, and I’d been rereading it at bedtime ever since. Like most of the nation’s ten-year-olds, I had an intense, private relationship with Snoopy, the cartoon beagle. He was a solitary not-animal animal who lived among larger creatures of a different species, which was more or less my feeling in my own house. My brothers, who are nine and twelve years older than I, were less like siblings than like an extra, fun pair of quasi-parents. Although I had friends and was a Cub Scout in good standing, I spent a lot of time alone with talking animals. I was an obsessive rereader of A. A. Milne and the Narnia and Doctor Dolittle novels, and my involvement with my collection of stuffed animals was on the verge of becoming age-inappropriate. It was another point of kinship with Snoopy that he, too, liked animal games. He impersonated tigers and vultures and mountain lions, sharks, sea monsters, pythons, cows, piranhas, penguins, and vampire bats. He was the perfect sunny egoist, starring in his ridiculous fantasies and basking in everyone’s attention. In a cartoon strip full of children, the dog was the character I recognized as a child.

Tom and my father had been talking in the living room when I went up to bed. Now, at some late and even stuffier hour, after I’d put aside the “Peanuts Treasury” and fallen asleep, Tom burst into our bedroom. He was shouting with harsh sarcasm. “You’ll get over it! You’ll forget about me! It’ll be so much easier! You’ll get over it!”

My father was offstage somewhere, making large abstract sounds. My mother was right behind Tom, sobbing at his shoulder, begging him to stop, to stop. He was pulling open dresser drawers, repacking bags he’d only recently unpacked. “You think you want me here,” he said, “but you’ll get over it.”

What about me? my mother pleaded. What about Jon?

“You’ll get over it!”

I was a small and fundamentally ridiculous person. Even if I’d dared sit up in bed, what could I have said? “Excuse me, I’m trying to sleep”? I lay still and followed the action through my eyelashes. There were further dramatic comings and goings, through some of which I may in fact have slept. Finally I heard Tom’s feet pounding down the stairs and my mother’s terrible cries, now nearly shrieks, receding after him: “Tom! Tom! Tom! Please! Tom!” And then the front door slammed.

Things like this had never happened in our house. The worst fight I’d ever witnessed was between Tom and our older brother, Bob, on the subject of Frank Zappa, whose music Tom admired and Bob one day dismissed with such patronizing disdain that Tom began to sneer at Bob’s own favorite group, the Supremes, which led to bitter hostilities. But a scene of real wailing and doors slamming in the night was completely off the map. When I woke up the next morning, the memory of it already felt decades-old and semi-dreamlike and unmentionable.

My father had left for work, and my mother served me breakfast without comment. The food on the table, the jingles on the radio, and the walk to school all were unremarkable; and yet everything about the day was soaked in dread. At school that week, in Miss Niblack’s class, we were rehearsing our fifth-grade play. The script, which I’d written, had a large number of bit parts and one very generous role that I’d created with my own memorization abilities in mind. The action took place on a boat, involved a taciturn villain named Mr. Scuba, and lacked the most rudimentary comedy, point, or moral. Not even I, who got to do most of the talking, enjoyed being in it. Its badness—my responsibility for its badness—became part of the day’s general dread.

There was something dreadful about springtime itself, the way plants and animals lost control, the “Lord of the Flies” buzzing, the heat indoors. After school, instead of staying outside to play, I followed my dread home and cornered my mother in our dining room. I asked her about my upcoming class performance. Would Dad be in town for it? What about Bob? Would he be home from college yet? And what about Tom? Would Tom be there, too? This was quite plausibly an innocent line of questioning—I was a small glutton for attention, forever turning conversations to the subject of myself—and, for a while, my mother gave me plausibly innocent answers. Then she slumped into a chair, put her face in her hands, and began to weep.

“Didn’t you hear anything last night?” she said.

“No.”

“You didn’t hear Tom and Dad shouting? You didn’t hear doors slamming?”

“No!”

She gathered me in her arms, which was probably the main thing I’d been dreading. I stood there stiffly while she hugged me. “Tom and Dad had a terrible fight,” she said. “After you went to bed. They had a terrible fight, and Tom got his things and left the house, and we don’t know where he went.”

“Oh.”

“I thought we’d hear from him today, but he hasn’t called, and I’m frantic, not knowing where he is. I’m just frantic!”

I squirmed a little in her grip.

“But this has nothing to do with you,” she said. “It’s between him and Dad and has nothing to do with you. I’m sure Tom’s sorry he won’t be here to see your play. Or maybe, who knows, he’ll be back by Friday and he will see it.”
