In "The Blind Assassin" by Margaret Atwood, the phrase "blood is thicker than water" emphasizes the importance of familial bonds over other relationships. It suggests that the connections we have with family are often deeper and more enduring than those with friends or acquaintances. This idea resonates with readers who understand the complexities of personal relationships and the loyalty that family can inspire, regardless of individual conflicts or differences.

Atwood's exploration of this theme reflects how shared history and experiences create a unique bond among family members. The quote encourages a reflection on the sacrifices and commitments made within these relationships, suggesting that despite life's challenges, the ties we share with family ultimately hold significant weight in our lives. This enduring truth highlights the complexity of love and loyalty present in human connections.
