My grandfather made my prom dress and then died five days later. When I walked into that room a girl took the skirt of it between her fingers and called it his curtains. Then the most popular boy in that school got up on the stage — and what he said had nothing to do with me.

PART 1 — CURTAINS

My grandfather brought me up from the age of six.

Ansel Brannick, sixty-eight, two jobs — a delivery round in the mornings and nights at a warehouse out on the Denbury road.

When prom came round I already knew what the answer was, because I had done the arithmetic myself, and I told him I would find something in the charity shop on Fenn Street and that I genuinely did not mind.

He hugged me and said, "Sweetheart, you'll have the best dress in that room."

I thought he meant his savings, and I said no, properly, twice.

And then for about five weeks he started coming in late. Later than the warehouse. Eleven, half eleven, and then he would be in the front room with the door shut until past midnight and I could hear something going in there.

I assumed it was the television.

Then on a Sunday in the April he called me in, took a dress out of the cupboard on a hanger with a sheet over it, and asked me to try it on.

I could not speak for about eleven seconds.

Deep green, floor length, a proper bodice with boning in it, and a seam finish inside that I did not understand the significance of until much later.

I said, "Grandad. Did you make this?"

And he said, "I had a bit of help."

Five days later he had a heart attack in the kitchen at ten past six in the morning and he was gone before the ambulance got to the end of our road.

I did not want to go to prom. I did not want to go anywhere.

My aunt Rhona said one thing about it, which was that the dress existed, and that it was going to exist whether I was in it or not.

So I went.

The Coverly Rooms. About a hundred and forty of us.

And I got about eleven steps into that room.

Corrine Vale was by the second table with three others and she saw me and her whole face lit up.

She came over, took the skirt of that dress between her finger and thumb, and lifted it about four inches, and rubbed the fabric like a woman in a shop.

And she said, loud, over the music, to about sixty people who could hear her:

"Give me that — let's see. It's a rag, Nell. Your grandad's curtains. Go home before somebody photographs it."

There was laughing. Not everybody. Enough.

I did not have anything. I was seventeen and he had been dead nine days and I had no words in my head at all.

I turned round to go.

And somebody took hold of my hand.

Roan Whitlock. Who I had said about four sentences to in five years.

He said, very quietly, "Stay there ten minutes. Don't leave."

Then he went up onto that stage and took the microphone off the DJ.

PART 2 — THE COAT

I need to put something in here before the rest of it, and I have not wanted to.

I was ashamed of my grandfather for about two years.

Not the whole time. Between about fifteen and seventeen.

He had a green work coat with a repair on the elbow that my grandmother did in 2009, and he wore it everywhere, and he picked me up from school in a van with a ladder rack on it.

And in the November of the year before he died, I asked him to park round the corner.

I did it nicely. I said something about the road being difficult to turn in.

He said, "Right you are," and he parked round the corner on Prewitt Street for seven months, and he never once mentioned it, and he never once got it wrong and pulled up outside.

Seven months of a sixty-eight-year-old man walking an extra two hundred yards in the dark after a double shift because his granddaughter did not want to be seen getting into his van.

That is the thing I would take back. Not anything anybody said at that prom.

Corrine Vale has apologised to me, in writing, and I will come back to that.

He never did anything that needed apologising for and I never gave him the chance to hear that I knew it.

PART 3 — FENN STREET

Here is what my grandfather actually did for five weeks, and I did not know one word of it until a quarter past ten at night in a hired ballroom.

There is an alterations shop on Fenn Street. It has been there since 1979 and it is run by a woman called Ottoline Prosser, who is seventy-four.

In the March, Ansel Brannick went in there and asked her what it would cost to have a dress made.

She told him. He did not have it.

So he asked her what it would cost to be taught.

And Ottoline Prosser said she was not a school, and he asked her whether her bins went out on a Tuesday.

For five weeks my grandfather swept that shop, took her deliveries round in his van, moved her stock, and put her bins out, and in exchange she taught him, four nights a week, from half nine until about midnight, after a full shift at the warehouse.

Twenty-one evenings.

She told me afterward that he was not good at it. She said his hands were too big and his eyes were going and he unpicked the bodice three separate times.

She also said that on the fourth night he asked her to teach him how to do a French seam, because he had read that it was what you did on the inside of a good dress, and that nobody would ever see it.

That is why the inside of that dress looks the way it does.

A sixty-eight-year-old man with a delivery round learned a finishing technique for the inside of a thing his granddaughter was going to wear once, so that if she ever turned it inside out she would find it had been done properly.

PART 4 — WHAT ROAN SAID

Roan Whitlock's grandmother is Ottoline Prosser.

He was in that shop most of those evenings. He does his homework in the back because it is quiet and because his mother works nights.

He sat eleven feet from my grandfather, four nights a week for five weeks, and neither of them ever mentioned it to me, and I did not know Roan Whitlock had a grandmother on Fenn Street.

What he did on that stage took about forty seconds.

He did not talk about me. He did not say my name more than once and he did not mention that my grandfather had died, which about half that room already knew and which the other half found out afterward.

He said — and I have this from four people and they all agree on the wording:

"I know who made that dress. He made it at my nan's shop on Fenn Street, four nights a week for five weeks, after a double shift, and he was rubbish at it, and he did the inside properly anyway."

Then he put the microphone down.

That is all. There was no speech and there was no lecture and he never said one word to Corrine Vale.

The room went completely silent. Somebody at the back started clapping and then a lot of people did, and I stood by the doors with my aunt's borrowed handbag and could not see anything.

Corrine Vale went the colour of the tablecloths and left about nine minutes later.

I have thought a great deal about why that worked when nothing else would have.

It is because he did not defend me. If he had got up there and said something about how she was beautiful and they were all horrible, it would have been about me, and I would have been the girl in the corner with a champion.

He got up there and made it about a man nobody in that room had ever looked at twice.

PART 5 — THE INSIDE

That was two years ago. I am nineteen.

Corrine Vale wrote to me in the November of that year, about seven months later, on paper, and it is two pages and it is not a good apology and it is a real one.

She says she knew exactly what she was doing and that she had been doing a version of it to me since we were thirteen. She does not explain why, because I think she does not know.

I have not replied and I do not think I am going to, and I have stopped feeling bad about that.

Roan and I are friends. That is all it is and I know what everybody wants it to be.

He is at college two hours away doing something with engines and he rings about once a fortnight and he has never once mentioned that night unless I have.

Ottoline Prosser taught me to sew.

Not as a gesture. I turned up at that shop in the July after he died because I wanted to be in a room he had been in, and I stood in the doorway and could not say what I wanted, and she said, "Well, the bins go out Tuesday."

I did two years of Tuesdays.

I am doing a textiles course now and I am not going to pretend that is the tidy ending it sounds like, because it is also the only thing I have found that makes an hour go past without my chest hurting.

The dress is in a bag in my wardrobe. I have worn it once since.

It's a rag, Nell. Your grandad's curtains.

She said that in front of about sixty people with the skirt of it between her finger and thumb, nine days after he died, and about fifteen people laughed.

And she was, in the only sense she meant, right about one thing: it was not a bought dress and everybody in that room could see it.

What she could not see, and what I could not see either until a boy said it into a microphone, is the inside of it.

There is a seam in that bodice that took a sixty-eight-year-old man three attempts and an extra evening to learn, for a surface that nobody was ever going to look at.

He knew I would not look at it. He did it anyway.
