There’s a word that captures a feeling many of us have experienced without always knowing how to name it: sonder. It’s the quiet realization that every person around you is living a life just as complex, chaotic, and meaningful as your own.
We move through our days surrounded by strangers—at the grocery store, in classrooms, on sidewalks, in traffic—rarely stopping to consider the depth of the lives passing beside us. Yet every single person we encounter carries their own memories, emotions, worries, dreams, and stories. Each person has faced moments that shaped them in ways we may never see.
It’s something I often find myself wondering about: what people’s stories might be.
No two lives unfold in exactly the same way. While we can share ideas, opinions, and experiences, no person will ever truly mirror another. Everyone carries a unique combination of challenges and triumphs. For some people, a moment of trauma for one individual might be a daily reality for another. That contrast alone reveals just how different—and how layered—our lives can be.
Think about a classroom, for example. You might sit beside the same people every day for months or even years, yet still know almost nothing about what they’re navigating beyond those walls. The person on your right might have just been accepted into their dream school. The person on your left might be quietly coping with the loss of someone they love.
From my own experience, I’ve often been surprised when I finally learn pieces of someone’s story. The lives people carry beneath the surface can be far more complicated than we ever imagined.
Despite everything people face, life keeps moving. Everyone continues to show up—to school, to work, to family gatherings, to everyday responsibilities—no matter what they may be carrying internally. That resilience is part of what makes humanity so fascinating.
It’s also what allows people with vastly different stories to come together around shared beliefs or causes. At a protest, for example, some individuals may show up to support an issue they care about, while others are there because they are living that issue every single day. Their reasons may differ, but their voices meet in the same space.
One image I once saw captured this idea perfectly. It was a photograph taken from above of a crowded traffic jam—dozens of cars packed together on the road. Above each vehicle were words describing what the driver inside might be going through at that exact moment.
Of course, the descriptions were imagined, but the message was powerful.
One car might hold someone on the way to a life-changing job interview. The car beside them might carry someone who had just received a terminal diagnosis. Another might contain a parent rushing to pick up their child. Another, someone grieving quietly after devastating news. From the outside, every car looked the same. Inside, entire worlds were unfolding.
It’s easy to assume that people who appear confident, successful, or even flawless must have easy lives. But often, those who seem the most put together have endured struggles that shaped them in ways we can’t see.
Whether someone is experiencing homelessness or standing on a red carpet, we all share something fundamental: we are human.
Every person walking past you was once someone’s baby. Every person has felt joy, fear, heartbreak, hope. And every person carries thoughts and emotions that remain largely invisible to the world around them.
That’s why the concept of sonder is so powerful. It reminds us that we may never fully understand what someone else is going through. Even the people we see every day can remain strangers in many ways. And sometimes, even those closest to us may be carrying experiences we have yet to see. There are billions of people in this world. Each one is living a life filled with moments, memories, and meaning.
And every day, their lives pass quietly beside our own.
