In Emily Bronte's "Wuthering Heights," after Catherine marries Edgar, they reside in Thrushcross Grange after their marriage. The Grange is described as a luxurious, elegant mansion that is in sharp contrast to the rugged and austere Wuthering Heights. Catherine is initially pleased with her new home, enjoying the comfort and refinement of her new surroundings. However, she soon begins to feel stifled by the Grange's social restrictions and the shallow lifestyle of its inhabitants. This is evident when she says, "I am Heathcliff! He's always, always in my mind: not as a pleasure, any more than I am always a pleasure to myself, but as my own being." This statement is a clear indication of her longing for the wild and unrestrained life she shared with Heathcliff at Wuthering Heights.
The contrast between Thrushcross Grange and Wuthering Heights symbolizes the difference between civilization and nature. Thrushcross Grange represents the civilized world of manners, wealth, and social conventions, while Wuthering Heights symbolizes the wild and natural world of instinct and passion. Catherine's dissatisfaction with her new home and yearning for her old life with Heathcliff shows the conflict between the constraints of civilization and the desire for the freedom of the natural world.
In conclusion, Catherine and Edgar reside in Thrushcross Grange after their marriage. Although Catherine initially enjoys the comforts of her new home, she later longs for the wild and unrestrained life she shared with Heathcliff at Wuthering Heights. The contrast between the two locations represents the conflict between civilization and nature, and Catherine's desire for the freedom of the natural world shows the tension between the constraints of society and the human desire for individual expression.
