Mel Robbins opens by explaining why family is harder to apply the Let Them Theory to than strangers or co-workers: family is permanent, blunt, and emotionally invested. Relatives feel entitled to their opinions because they have known you longest, and families operate as interconnected systems where any change—divorce, career shifts, new partners, blended families—sends shock waves through every relationship. She emphasizes that recognizing this larger context helps you stay in control of how you show up.

Robbins gives focused advice to stepparents: Let Them grieve, Let Them see you as a threat, Let Them have alone time with their parent, and Let Them dislike you. Stepchildren are mourning the family they wanted, and grace from the adult creates space for the dynamic to evolve. The core principle is the same across family contexts: don't try to change relatives' opinions; give them freedom to hold them, then choose your own response.

She introduces the Frame of Reference tool, shared by her friend Lisa Bilyeu—understanding the lens through which someone sees a situation. Robbins illustrates with her mother's lukewarm reaction to her engagement to Chris. For years, Mel felt unsupported. Applying Frame of Reference, she now understands her mother had left her own family at 17, raised kids far from relatives in isolation, and feared losing Mel to the East Coast—a fear that came true. Her mother's reaction wasn't judgment; it was grief. Both women were right because they had different Frames of Reference.

Robbins extends the lesson by acknowledging she would feel similarly if her own daughters Sawyer or Kendall settled far away. Stepping into someone's lens may not change opinions, but it deepens connection and dissolves power struggles, replacing them with understanding. She acknowledges this is a deeply personal choice, especially when opinions are hurtful or bigoted, and the reader must decide whether to keep someone in their life.

She urges readers to accept that most people haven't done inner work and can only meet you as deeply as they've met themselves. Let parents, siblings, and in-laws be who they are—they aren't changing. Acceptance isn't surrender; it's reclaiming power to shape the future. The Let Me half asks readers to define the relationship they want based on their values: showing up out of love rather than guilt, having hard conversations, forgiving, or creating distance.

The chapter closes by summarizing the section on fearing others' opinions: the problem is giving opinions too much power; the truth is people will judge no matter what; the solution is aligning thoughts and actions with your values so you become proud of yourself and stop caring what others think.
