In Annie Proulx's "Postcards," the imagery of a house's windows glowing in the night is vividly depicted with a simile that likens them to melting butter. This description creates a warm and inviting atmosphere, contrasting with the surrounding darkness. It evokes feelings of comfort and familiarity, suggesting a refuge or a home that stands out in the bleakness of night.

The use of such a striking comparison highlights the beauty found in the mundane. This line encapsulates the essence of home, portraying it not just as a physical space but as a source of warmth and safety amidst solitude. The shimmer of the windows acts as a beacon, drawing attention and eliciting a sense of peace in a potentially lonely environment.
