When people ask me what I do—taxi drivers, hairdressers—I tell them I work in an office. In almost eight years, no one’s ever asked what kind of office, or what sort of job I do there. I can’t decide whether that’s because I fit perfectly with their idea of what an office worker looks like, or whether people hear the phrase work in an office and automatically fill in the blanks themselves—lady doing photocopying, man tapping at a keyboard. I’m not complaining. I’m delighted that I don’t have to get into the fascinating intricacies of accounts receivable with them. When I first started working here, whenever anyone asked, I told them that I worked for a graphic design company, but then they assumed I was a creative type. It became a bit boring to see their faces blank over when I explained that it was back office stuff, that I didn’t get to use the fine‑tipped pens and the fancy software.

I’m nearly thirty years old now and I’ve been working here since I was twenty‑one. Bob, the owner, took me on not long after the office opened. I suppose he felt sorry for me. I had a degree in Classics and no work experience to speak of, and I turned up for the interview with a black eye, a couple of missing teeth and a broken arm. Maybe he sensed, back then, that I would never aspire to anything more than a poorly paid office job, that I would be content to stay with the company and save him the bother of ever having to recruit a replacement. Perhaps he could also tell that I’d never need to take time off to go on honeymoon, or request maternity leave. I don’t know.

It's definitely a two-tier system in the office; the creatives are the film stars, the rest of us merely supporting artists. You can tell by looking at us which category we fall into. To be fair, part of that is salary­ elated. The back office staff get paid a pittance, and so we can't af­ford much in the way of sharp haircuts and nerdy glasses. Clothes, music, gadgets-although the designers are desperate to be seen as freethinkers with unique ideas, they all adhere to a strict uniform.

Graphic design is of no interest to me. I'm a finance clerk. I could be issuing invoices for anything, really; armaments, Rohypnol, co­conuts.

From Monday to Friday, I come in at 8.30. I take an hour for lunch. I used to bring in my own sandwiches, but the food at home always went off before I could use it up, so now I get something from the high street. I always finish with a trip to Marks & Spencer on a Friday, which rounds off the week nicely. I sit in the staffroom with my sandwich and I read the newspaper from cover to cover, and then do the crosswords. I take the Daily Telegraph, not because I like it particularly, but because it has the best cryptic crossword. I don't talk to anyone–by the time I've bought my meal deal, read the paper and finished both crosswords, the hour is almost up. I go back to my desk and work till 5.30. The bus home takes half an hour.

I make supper and eat it while I listen to the Archers. I usually have pasta with pesto and salad–one pan and one plate. My childhood was full of culinary contradiction, and I've dined on both hand-dived scallops and boil-in-the-bag cod over the years. After much reflection on the political and sociological aspects of the table, I have realized that I am completely uninterested in food. My preference is for fodder hat is cheap, quick and simple to procure and prepare, whilst provid­ing the requisite nutrients to enable a person to stay alive.

After I've washed up, I read a book, or sometimes I watch televi­sion if there's a program the Telegraph has recommended that day. I usually (well, always) talk to Mummy on a Wednesday evening for ten minutes or so. I go to bed around ten, read for half an hour and then put the light out. I don’t have trouble sleeping, as a rule.

On Fridays, I don’t get the bus straight after work but instead I go to the Tesco Metro around the corner from the office and buy a margherita pizza, some Chianti and two big bottles of Glen’s vodka. When I get home, I eat the pizza and drink the wine. I have some vodka afterward. I don’t need much on a Friday, just a few big swigs. I usually wake up on the sofa around 3 a.m., and I stumble off to bed. I drink the rest of the vodka over the weekend, spread it throughout both days so that I’m neither drunk nor sober. Monday takes a long time to come around.

My phone doesn’t ring often—it makes me jump when it does—and it’s usually people asking if I’ve been mis‑sold Payment Protection Insurance. I whisper I know where you live to them, and hang up the phone very, very gently. No one’s been in my flat this year apart from service professionals; I’ve not voluntarily invited another human being across the threshold, except to read the meter. You’d think that would be impossible, wouldn’t you? It’s true, though. I do exist, don’t I? It often feels as if I’m not here, that I’m a figment of my own imagination. There are days when I feel so lightly connected to the earth that the threads that tether me to the planet are gossamer thin, spun sugar. A strong gust of wind could dislodge me completely, and I’d lift off and blow away, like one of those seeds in a dandelion clock.

The threads tighten slightly from Monday to Friday. People phone the office to discuss credit lines, send me emails about contracts and estimates. The employees I share an office with—Janey, Loretta, Bernadette and Billy—would notice if I didn’t turn up. After a few days (I’ve often wondered how many) they would worry that I hadn’t phoned in sick—so unlike me—and they’d dig out my address from the personnel files. I suppose they’d call the police in the end, wouldn’t they? Would the officers break down the front door? Find me, covering their faces, gagging at the smell? That would give them something to talk about in the office. They hate me, but they don't actually wish me dead. I don't think so, anyway.

I went to the doctor yesterday. It feels like eons ago. I got the young doctor this time, the pale chap with the red hair, which I was pleased about. The younger they are, the more recent their training, and that can only be a good thing. I hate it when I get old Dr. Wilson; she's about sixty, and I can't imagine she knows much about the latest drugs and medical breakthroughs. She can barely work the computer.

The doctor was doing that thing where they talk to you but don't look at you, reading my notes on the screen, hitting the return key with increasing ferocity as he scrolled down.

"What can I do for you this time, Miss Oliphant?"

"It's back pain, Doctor," I told him. "I've been in agony." He still didn't look at me.

"How long have you been experiencing this?" he said.

"A couple of weeks," I told him.

He nodded.

"I think I know what's causing it," I said, "but I wanted to get your opinion."

He stopped reading, finally looked across at me.

"What is it that you think is causing your back pain, Miss Oliphant?"

"I think it's my breasts, Doctor," I told him.

"Your breasts?"

"Yes," I said. "You see, I've weighed them, and they're almost half a stone-combined weight, that is, not each!" I laughed. He stared at me, not laughing. "That's a lot of weight to carry around, isn't it?" I asked him. "I mean, if I were to strap half a stone of additional flesh to your chest and force you to walk around all day like that, your back would hurt too, wouldn't it?"

He stared at me, then cleared his throat.
