“Am I my brother’s keeper?” It’s an ancient question that echoes through time. In today’s world, where so many rush past one another with their eyes on their own paths, it can be easy to forget the responsibility we share for the people around us…especially the most vulnerable. But recently, in White House, Tennessee, a 12-year-old girl answered that question with her actions: Yes, I am.

The story begins with nine-year-old Liam Cooper, a boy full of life who happens to be profoundly on the autism spectrum. Liam was diagnosed at Level 3, meaning he requires significant daily support and he communicates primarily in single words. Liam loves to ride his scooter up and down the driveway in a routine that makes sense to him, and he has an adventurous spirit that sometimes propels him beyond his family’s watchful eyes.

Despite locked doors, alarms, and fences, Liam has managed to wander from home several times. His mother, Kiri Cooper, describes those moments as every parent’s nightmare. “We’ve had several incidents,” she said. “The first time, the police had to bring him home. He knows how to open locks and climb fences, he’s also strong, athletic, and determined.”

Liam’s escapes are especially frightening because he doesn’t like wearing clothes or shoes. “He lives in his underwear,” Kiri explained. “That’s how he feels most comfortable.” Imagine, then, a barefoot boy in underwear dashing through streets and yards, while a family frantically searches and prays for help.

One afternoon just weeks ago, Liam hopped on his scooter and rode farther than ever before…straight down the street and out of sight. As adults drove by, many slowing just enough to squeeze past, a sixth-grade girl named Emma noticed what was happening.

Emma had just gotten home from soccer practice and was still wearing her cleats. Without a second thought, she kicked them off, planted her bare feet on the pavement, and sprinted after Liam. She waved her arms at cars, begging for help. But shockingly, drivers ignored her. One even rolled down a window and asked what was wrong, only to reply, “Well, I guess you better keep running.”

And so she did. Emma ran, determined to keep Liam safe until someone else cared enough to help. Eventually, another neighbor recognized her and stopped, helping to corral Liam until police arrived.

“She was his guardian angel that day,” Kiri said. “She didn’t hesitate. While adults looked away, a 12-year-old girl threw off her shoes and ran.”

The reality of life with autism is complex, unpredictable, and often misunderstood. Kiri has faced unkind comments online from people suggesting she “just put buzzers on the doors,” unaware she already has multiple alarms and locks installed. “It’s not as simple as people think,” she said. “You can prepare for everything and still face the unknown.”

But for every insensitive comment, there are dozens of moments of grace. The neighbor, drinking coffee, who spotted Liam racing through a creek bed. The police officers who always respond quickly. And now, a girl named Emma who saw someone in need and refused to let him go on alone.

What does it mean to be our brother’s keeper? Sometimes it looks like noticing when a child is vulnerable. Sometimes it means stopping your car when you see a girl barefoot and frantic in the street. And sometimes, it means doing exactly what Emma did…throwing off your shoes and running, doing the right thing no matter what anyone else does.

Love and responsibility aren’t just for families. They are for communities. For neighbors. For each one of us.

Liam’s story is not just about the challenges of autism or the heartbreak of being ignored. It is also about the beauty of compassion, and how even the smallest acts of courage, especially from the youngest among us, can change everything.

So, when we ask, “Am I my brother’s keeper?” we don’t have to look far for the answer. We need only remember the day a sixth-grade girl named Emma said, 'Yes, I am.'
