The quote "A heart can be broken but it keeps on beating just the same" from Fannie Flagg's "Fried Green Tomatoes at the Whistle Stop Cafe" illustrates the resilience of the human spirit. Even after enduring emotional pain and heartbreak, life continues, and people find ways to carry on. This reflects a larger theme in the book, where characters face various hardships yet manage to persevere and find joy amidst suffering.
