was saying, as he had been thinking about a row which had blown up at the officeâStuart was a statistician in the Scottish Executiveâand there had been an intense discussion in an internal meeting of how figures might be presented. The optimists had been pitted against the pessimists, and Stuart was not sure exactly into which camp he fitted. He believed that there were sometimes grounds for optimism and sometimes grounds for pessimism, and that one might on occasion choose between them at the level of subtle, and permissible, nuances but in general should stick to the truth, which was often uncomfortable.
All of this was some distance away from the matter which Irene was talking about, which was the issue of how their son, Bertie, the remarkably talented five-and-three-quarter-year-old, should get from Scotland Street, where they lived, to the school in Merchiston, in which he had now been enrolled.
âObviously I shall go with him for the first year or so,â said Irene. âAnd Iâll pick him up at three in the afternoon or whenever it is that he finishes. But before we know where we are heâll be big enough to go by himself, and weâll have to make a decision.â
âAbout what?â Stuart asked, distractedly.
Irene felt vaguely irritated. There were times when Stuartâs mind seemed to be less focused than it might. And these occasions, she had noticed, were increasingly occurring when she was talking about something important to do with Bertie. Was he fully committed to the Bertie project? She would have to talk to him some time about that. One did not raise a little boy like Bertie without full commitment from both parents, and that meant a full commitment to all aspects of the project: educational, social and psychological.
âAbout which bus he takes,â she said, the irritation creeping into her voice. âThere are several possibilities, as you know. The 23 or the 27. And thereâs also the number 10 to be thought about.â
Stuart shrugged. âWhich goes closer to the school?â he asked.
âThe 27,â said Irene. âBoth the 23 and the 27 go up Dundas Street and on to Tollcross. Then the 23 carries on up to Morningside, whereas the 27 turns right at the Kingâs Theatre and goes along Gilmore Place to Polwarth.â
âOh,â said Stuart.
Irene looked out of the window, staring, while she spoke, at a window on the other side of the street. A woman stood at this window, brushing her hair. âIf he took the 23,â Irene went on, âhe would get off in Bruntsfield and then walk along Merchiston Crescent and down Spylaw Road. It would take him about ten minutes to reach the school gate. Alternatively, if he took the 27, he would have a walk of about four minutes from a stop on Polwarth Terrace.â
âAnd the 10?â
âThe number 10 is a different proposition,â said Irene. âThat bus goes along Princes Street and ends up on Leith Walk. If he took that, he would have to walk along London Street and then up to the top of Leith Walk. Itâs a slightly longer route, but thereâs another factor involved there.â
Stuart raised an eyebrow. The ethics of statistical presentation seemed simple in comparison with the complexities of Edinburgh bus routes. âAnd this factor? What is it?â
âGoing along London Street would remind him of the walk to the nursery school,â she said quietly. âThatâs the route which I took him to thatâ¦that place.â She shuddered involuntarily, remembering her last confrontation with the nursery-school teacher, and that awful morning when Bertie had finally been suspended for writing graffiti, in Italian, in the childrenâs toilets. That had been so unfair, so cruel. It was entirely natural for small boys to explore their environment in this way and to seek to express themselves. If there were any fault involved, then surely it was that
