We all remember that one special teacher…

Mrs. Korthaus has always been ahead of her time—an educator who inspired her students to dream bigger, think deeper, and live boldly. For decades, she led an English classroom with caring and conviction, but it’s not until she’s retired, and then fighting cancer, that she begins to share her story: long ago marching with Dr. Martin Luther King Jr., building a corporate career, and overcoming heartbreak before “accidentally” becoming a teacher and forever shaping the lives of countless young adults—including bestselling author Kristine Gasbarre.

In Show, Don’t Tell, Kristine reflects on her thirty-year friendship with this extraordinary teacher, celebrating profound lessons of self-discovery, resilience, strength, and showing up fully for life. Mrs. Korthaus’s enduring wisdom on carving out one’s own path with adventure and relentless faith delivers a moving reminder about the elders who’ve believed in us—and a call to thank them for the lives they influenced us to lead.
