In Bill Bryson's "Icons of England," the quote evokes a deep sense of comfort and nostalgia despite the harshness of winter. The imagery of a cold night and chilling winds paints a stark picture of the outside world, with the Thames winding through the landscape, highlighting nature's unforgiving aspects.
However, the contrast comes from the warm feelings associated with the old house, suggesting a refuge from the cold. This warmth symbolizes not just physical comfort but also emotional security, reflecting the bittersweet nature of cherished memories during challenging times.
