He had to do it now; it felt horrible and uncomfortable when he tried to stop, even just to see what it was like walking down a street breathing "normally'. It was like the feeling he used to get when he played another game from his childhood; that of closing his eyes and walking for a certain number of steps along, say, a wide path in a park. No matter how certain he might be immediately before he closed his eyes that there was plenty of space in front of him, no matter how positive he was as he walked with eyes closed that he wasn't veering off to one side and there was tarmac under his feet rather than grass, he still found it very hard, almost impossible, to walk more than about twenty paces with his eyes closed. He would be certain, positive, that he was about to walk into a tree, or a post or sign he hadn't noticed; even that somebody had been watching from behind a tree and was about to leap out and punch him hard on the nose.

Better to keep your eyes open; better to trust your instincts and take deep breaths between the parked cars. You couldn't be too careful.

He got to the car and stopped opposite it, breathing deeply. He took off his hard hat and wiped his brow, after checking for scaffolding. The safety helmet was another of his discoveries, his good ideas. He knew how vulnerable people's heads were, and how important his own was. He knew they would just love to arrange a little "accident" with some spanner or brick falling from a building, or, more plausibly still, from some scaffolding. So he had worn that hard hat, since even before he left the home. No matter what the job was, or what else he might be doing, he wore the hat when he was outside. They had laughed at him in the road gang; who did he think he was? they said. Poncy engineers wore hard hats everywhere, not your labourers. Or was he frightened of pigeons then? Going a bit thin on top as well as inside, eh? Ha ha. Let them laugh. They wouldn't get the hat off him. He had two spare hats in his room just in case he ever lost his usual one, or somebody stole it. People had done that before now, too.
