"I married up several times. And then across once or twice. And then beneath me. I never quite found the right level somehow."

This quote illustrates a metaphorical perspective on marriage, suggesting the speaker experienced unions with individuals of varying social or personal standing. The playful mention of marrying diagonally or in a curved direction emphasizes the unpredictability and complexity of relationships, hinting at the search for the ideal connection. The author, John Boyne, uses this humorous and whimsical language to reflect on the challenges of finding the perfect match. It underscores themes of personal growth, social navigation, and the humorous side of life's romantic pursuits in "The Heart's Invisible Furies."
