The quote from Margaret Atwood's "The Blind Assassin" reflects on the complex nature of companionship in the face of fear and mortality. The speaker acknowledges the haunting presence of death, suggesting that walking alongside someone offers a sense of security. However, this sense of safety is fleeting, as the "Thou" symbolizes the unpredictability and elusiveness of support in difficult times.

This contemplation reveals a deeper truth about relationships; even when we feel less alone with another person, the fear of abandonment remains. The speaker's experience indicates that those we rely on may not always be present, leading to a sense of vulnerability. The reflection underscores the tension between seeking comfort in others while confronting the inevitability of isolation in challenging moments.
