The Long Game · Part 2 of 6

Factor of Safety

6 min read

I refreshed the donation page eleven times before I got out of bed. It went up every time.

$31,406. $31,980. $33,115. Overnight, while I slept, strangers had sent the Hairloom wig charity more money than our team had raised in all of recorded history.

I am Dagny Gundersen, a thirty-seven-year-old hydraulic engineer. The day before, I had bet my twenty-year-old hair on a number I considered physically unreachable. I had applied a factor of safety of thirty.

The factor of safety had failed overnight. In my field, that is called an incident report.


The video had 2.4 million views by seven o'clock.

I watched it once, in my kitchen, with the sound low as if someone might overhear. There I was at the whiteboard, explaining the wet weight of my own braid. There was the arrow. I had not realized how much I gestured at the arrow.

The comments were mostly kind and entirely baffling.

She said "distributed load" about her HAIR.

Fourteen dollars and eighty cents. She knows her hair's water bill. I would die for her.

Can she inspect my house next.

I don't even have a pump station and I feel safer.

Somebody had already made the clip into a song. Somebody else had made a diagram of the anchorage, with all four pins labeled. They had labeled one pin wrong. I wanted very badly to correct it, and I did not, which I would like noted as personal growth.

By breakfast, the internet had given me three nicknames. The Braid Engineer and Load Calc Lady were accurate. One big account went with Rapunzel With a License. I decided I could live with two of them.

My mother texted at 7:15. Is this you on my phone?? Then, a minute later: I still have the scissors.

I did not reply. Some messages are better left on read until you have had coffee.


At the Water Authority, the security guard at the front desk looked up when I came in. He looked at my head. Then he looked at his phone, and then back at my head, like someone checking a part number.

"Morning," he said. "Safe travels."

I have no idea what that meant. I don't think he did either.

Upstairs, the whole team was already in the conference room. That had never happened before nine.

Osman had brought a coffee for everyone. Lucia was sitting very straight, like a student outside a principal's office. Rocco stood by the window, his shaved head shining under the fluorescent lights.

Winifred sat at the head of the table with both pairs of glasses on.

"Sit," she said. "Before anyone says anything, I want to make one thing clear."

I sat.

"A bet made in a staff meeting," Winifred said, "is not a contract. I checked. I called Legal at seven-fifteen this morning. Legal was not happy to hear from me at seven-fifteen, but Legal agrees."

"Respectfully," Rocco said, "nobody in this room is holding scissors. If anyone ever does, I will personally escort them out."

"I can take the video down," Lucia said. Her voice was small. "Caption: junior engineer feels terrible."

"Don't take it down," I said. "It's raised thirty-three thousand dollars for Hairloom."

"Thirty-six," Osman said, looking at his laptop. "Let me pull up the map."

He pulled up the map. It was a map of the world, with a small blue dot for every donation, in forty-one countries. There was a dot in a town in Iceland with a population, according to Osman, of two hundred and six.

"Six dollars from Iceland," Osman said. "About three cents a person. That's commitment."


Here is what I need you to understand about me. I keep my word. Not as a moral principle, although it is that too. I keep my word because a promise is just a specification, and I have spent my whole career meeting specifications.

If a drawing says a pipe carries eight hundred gallons a minute, it carries eight hundred gallons a minute. You do not get to say later that you were joking about the pipe.

But I had also not decided anything. I had made a bet because I thought I would never have to think about it. Now I had to think about it, in public, with my head on two million phones.

So I did what I always do when a design gets complicated. I stood up, took the blue marker and wrote on the whiteboard.

DECISION: PENDING.

OWNER: D. GUNDERSEN.

SCHEDULE: WHEN IT'S READY.

"That's a design review," I said. "Nobody else gets a vote. Not the bet, not this team and not the internet. I'll decide when I've decided."

"Noted," said Winifred, and wrote it down.

"Caption," said Lucia, sounding better. "Senior engineer issues a spec."


Ramona Hedlund called at eleven.

I had expected Hairloom to email. Instead, the founder phoned the main line, and the receptionist transferred her to me with the tone of someone handing over a live grenade.

"Darling," said Ramona. "Is this the Braid Engineer?"

Her voice was big and warm and slightly theatrical. I later learned that she was sixty-eight and had spent thirty years building wigs for an opera company before starting Hairloom. She describes everything as if it were a scene in a play.

"This is Dagny," I said.

"Dagny. We are in the second act, darling. Our website crashed twice this morning, and my volunteers are weeping into the wig stands.

"Do you know what fifty thousand dollars does for us?"

"We're at thirty-eight."

"I'm rounding up with my heart," she said. "It means we can pay for medical-grade wig caps for every client this year. It means nobody waits. It means I can stop buying glue from a catalog that also sells fishing lures."

Then her voice got quieter. It was the first and only time I ever heard Ramona speak below a stage whisper.

"Now listen to me," she said. "We want your money. We do not need your hair.

"Your hair belongs to you. Nobody from Hairloom will ever ask you for it. If anyone uses our name to pressure you, you call me, and I'll handle it."

"Thank you," I said. I meant it more than I could explain over the phone.

"Also," said Ramona, "if you ever do want to donate, it needs twelve inches, clean and dry, in a braid or ponytail. Not that I'm asking. I'm just giving you the spec."

"You've done your research."

"Darling," she said, "I read your whiteboard."


The afternoon was a long, slow climb.

$41,000 by lunch. $44,500 by three o'clock. Nobody on the second floor got any work done. Osman's map now had so many dots it looked like a weather system. Lucia refreshed the page so often she sprained something in her thumb.

I tried to review a drainage report for a new subdivision. I read the same paragraph about culvert sizing four times. People kept walking past the conference room to peer through the glass at my head. They looked at it like a museum exhibit about to be moved.

At 4:40 the total said $49,870.

Rocco had gone quiet about an hour earlier. He was sitting at his desk with his hands folded on top of his head, like a man protecting a nest.

"You're quiet," I said.

"Respectfully," said Rocco, "I'm not quiet. I'm calculating."

"Calculating what?"

"How fast hair grows," he said. "I haven't had any since 1998. I don't know the rate."

"Half an inch a month," I said. "Roughly. It varies."

He looked at me with real fear.

"What happens at the length where you need a comb? Is there a number? Is it on a chart?"

"It's on a chart."

At 4:47, the page refreshed itself. A donor in Ohio had sent forty dollars with the message for the bald guy.

The total read $50,010.

The whole floor went silent. Winifred came out of her office holding her notebook and opened it to Monday's page. She did not say anything. She just turned it around so that Rocco could read his own sentence, in her handwriting, underlined twice.

If we hit fifty, I'll grow mine.

Rocco touched the top of his head, the way you check a pocket for your keys.

"Winifred," he said slowly. "What exactly did Legal say about bets made in staff meetings?"

Winifred put her glasses on. Both pairs.

"I only asked about Dagny's," she said.
