Given that neither Jane nor Bill are naturally quick-witted or particularly well-educated, they feel inferior to their bright son. Moreover, Harold shows an enthusiasm for attending church and studying Scripture that they, too, lack, judging by how impressed they are by his zeal. While a merely average intellect and interest in religion aren’t necessarily shameful, Harold’s parents feel especially sensitive given their lower-class origins and the more prosperous rank they now occupy, as Jane will later testify. They don’t want Harold to be conscious of their less sophisticated and enlightened background, so they substitute a successful salesman’s profession for Bill’s coarser livelihood.
