Michael smiled tolerantly. The front part of his brain said: my friend's body has run away with him. It's hormones, it means nothing. Michael fooled himself into thinking Al needed reassurance, that it made no difference to him. Michael chuckled and gave the head of the penis an admonitory tap, as if to say: I don't mind, but put it away, mate.

By now Michael lived in terror of his sexuality. Michael had conjured out of his big athletic body a big forgiving athletic heterosexual. The heterosexual lived and breathed and took Michael's place whenever he was needed.

Al, shame-faced, turned his back to him and dressed, hunched and quiet.

But Michael could not be acting all the time. He must have been sending signals. He must have looked into Al's eyes at lunchtime, and smiled a big kind loving smile, all unawares. Once in the boys' toilets next to the showers Al walked past Michael's cubicle. The cubicles had no doors and were open to view so teachers could check for smoking or drugs. Al stopped and smiled, and Michael, caught as he was on the toilet, his dick jammed down between his legs, couldn't help but grin back. In that grin, he could feel all of his yearning flash out of him like a sword. There was complicity in that grin; I like being naked around you. He felt his legs unclench and open.

Some time later, Al invited Michael back to his studio. It was tiny, with big windows with net curtains pulled back. Anyone on the street could see them. That meant nothing to Al. He lolled like a tongue on his double bed, having changed into something comfortable: a T-shirt and very tight satiny blue running shorts.

Michael was trying to be good. This nice innocent boy, he told himself: Michael, keep your eyes to yourself. Al tapped the bed for Michael to sit next to him. Michael perched on its edge at a distance from him. He didn't want to take advantage.

Al heaved slightly on the bed, arching his back. 'My parents are worried about my living alone. They are frightened that I might meet a homosexual.'

'Where do parents get their ideas from? I mean, even if you did, it's no big deal, and if the guy wanted anything you could just say no, right?'

Al nodded, holding his chin up. 'I could, yeah.' He edged closer to Michael. 'Have you ever met anyone… like that?'

'Naw,' said Michael, going into big and butch mode. 'No, I never.'

And in big, blurting butch mode Michael had stood up, afraid, away from the bed.

Al had sat up too, and suddenly swung his feet onto the floor. A few more things were said, and then Al announced, his face closed and wary, 'Anyway, I got my homework to do.'

And outside the studio flat, Michael stopped. Next door was the newsagents where Michael glanced up nervously at Gay Times. He had to lean against the wall, and he nearly doubled over in rage. At first, he thought that he was outraged that a pass had been made at him. Then he thought he was enraged at the betrayal of Tabitha. Then he was mad at himself and mad at Al, and he did not know why. A blinding headache spread across the breadth of his forehead.

Michael could not remember what happened afterwards. He and Al seemed to stop talking. Something happened to Al during the last year at school. Michael saw it only from afar. Al didn't study for exams. His dark eyes were clouded and encircled with bags of even darker flesh. His tie was askew, his school uniform was untended. Al wore it with the bitter swagger of the unloved, the outcast. He dyed his hair a muddy, brassy blond.

Michael supposed it went something like this: my adopted parents do in fact care about me. They know I am stranded between two cultures. They don't want me to have to guess where my birth parents were from, and read about those cultures in books. They are worried that I will have no self-esteem. They are concerned that I am young and needing to be constantly reassured, partly because they deserted me. My parents would be horrified to know that I am haunting parks and toilets and taking older men back to my flat and spending all night in clubs. They don't want me getting into drugs and cock rings. It's just that my parents won't do a single thing to stop it.

Sometime before A-levels, Al simply stopped coming to school.

Michael still had fantasies that he had become Al's lover and ended up living with him. They would have moved to Sussex together and found a bedsit in Brighton and Michael would have gone to university and Al to art school. He could see the Cure posters on their wall and smell the curries they would have cooked together.

Michael kept an eye out for Al. He had no interest in clothes, but he read the fashion pages even so. Michael saw young British-Turkish designers become famous, he saw young Italian-British designers move to French couturiers. Al was not among them. From time to time he looked in the telephone directory for Al Wilcox, or rather Ali Wilcox. He looked at the photograph of any young Indian designer, in case Al had changed his name. Silence.

And something in that silence delayed him calling up an Angel now. He had felt that kind of silence before when calling up an Angel.

What was it that someone said? Fashion was moving in circles now because all the talented young designers had died?

If Michael had said yes to Al, if they had become lovers, would it have made any difference? Would Al be alive? It would have made a difference to Michael. He could have practised being in love, making a home, being human and close. Even if it had come to nothing, he would have begun to grow up at seventeen.

I have a feeling Al can make no difference now to anything.

Michael came home from a day back at the university sitting final exams and telling students to turn off their mobile phones. He sat in his darkened sitting room and thought about Al. He crunched a Viagra like candy, and waited for his hour.

He was a little bit scared, and that was good. Being scared, Michael had realized, means you're learning. I can edit this like a film, Michael thought. I can cut to the chase.

The air swung back like a locker door, and Al stood revealed, naked and solemn. His eyes were frightened and serious. This was nothing like a body running away with itself on automatic erection. This was a needy seventeen-year-old who had made a decision that required him to show who he was.

'Come here,' said Michael. 'Sit next to me.'

Al came to the sitting-room sofa, and curled up like a baby, caching his nakedness and resting his head on Michael's lap. 'I missed you,' Al said. 'I missed you for a long time.' Al lay still, and closed his eyes with what looked like relief. 'You didn't get fat. You didn't get boring. You stayed Michael.'

Michael found he was able to lean all the way down to kiss the top of Al's head. 'What happened to you?' he asked.

Al said. 'I missed the train.'

'What does that mean?'

'Oh. It means I died.'

Michael's heart groaned. Not another one. Michael's heart was fed to bursting with this stuff. It was like the war, his gay generation's war. Why didn't it stop?

'How old?' Michael whispered.

'Twenty-one. One of the very first in London.' Al, still curled up, raised a hand as if volunteering. 'They didn't even know what it was.'

Michael had broken out into a sweat and he made a shrugging motion as if he were in harness.

Al's eyes glittered up at him. 'Why did you turn me down, Michael? I wanted to be with you.'

Michael said, 'Because I think that if I make a pass at someone, I'll kill them.'

The words popped out, like a pip squeezed from an orange under stress, hard and bitter and glossy. Michael ran a hand over his brow. The words, he realized, were true. Michael chuckled. It was a strange kind of laugh that bent him over in the middle.

'Now it looks like I kill people if I don't make a pass at them.' He managed a sick sad smile.
