You probably remember the song. Or maybe it's just the way Big Bird tilts his head when he's confused. For over fifty years, kids have been tuning in to find out one specific thing: how to actually get along with other humans. When we talk about Sesame Street what is friend and how the show defines it, we aren't just talking about sharing toys or saying "please." We are talking about a massive, decades-long psychological experiment designed to make us less lonely.
It’s deep.
Honestly, the show handles friendship better than most HR departments. While adults are out here ghosting each other or "networking," Elmo and Abby Cadabby are doing the heavy lifting of defining what it means to be a "friend" in a world that can be pretty confusing. It’s not just about being nice. It’s about the messy stuff—the apologies, the boredom, and the moments when you realize your friend is a grumpy monster who lives in a trash can.
The Evolution of Friendship on the Street
In the early days, back in 1969, the creators at Children's Television Workshop (now Sesame Workshop) weren't just guessing. They worked with Harvard psychologists like Gerald Lesser to figure out how to model prosocial behavior. They realized kids don't learn friendship by being lectured. They learn it by watching.
Take Bert and Ernie. They are the ultimate case study. They are total opposites. One likes pigeons and oatmeal; the other wants to play the saxophone at 3:00 AM and talks to a rubber duck. They argue. A lot. But the core of their "friend" status isn't that they agree—it's that they stay. They show that you don't have to be identical to be inseparable.
Sesame Street: What is Friend? (It’s More Than Just Playing)
When a kid asks "what is friend," they are usually asking "is this person going to be mean to me?" Sesame Street answers that by showing that friendship is an active verb. It’s a series of choices.
The Big Bird and Snuffy Dynamic
For years, Snuffleupagus was Big Bird’s "imaginary" friend. When the adults finally saw him in Season 17, it changed the show's DNA. This wasn't just a gimmick. The writers realized that having a friend who only you understand is a huge part of childhood development. It validated the internal life of a child. Friendship on Sesame Street is often about being the one person who believes in someone else when no one else does.

Learning to Be "For-Real" Friends
Sometimes friendship sucks. You get your feelings hurt. Someone breaks your favorite crayon. The show doesn't shy away from this. There’s a famous episode where Big Bird is frustrated with Snuffy, or where Oscar the Grouch is... well, himself. The "friend" definition here includes conflict resolution. It’s about the "I’m sorry" and the "It’s okay."
Basically, if you can’t navigate a disagreement, you aren't really friends yet. You're just acquaintances who share a sandbox.
Why Diversity is the Secret Sauce
You can’t talk about Sesame Street what is friend without talking about the humans. Gordon, Susan, Bob, Maria, Luis. These weren't just background characters. They modeled a multi-generational, multi-ethnic community where the definition of a friend extended across every possible boundary.
In the 1970s, seeing a diverse group of adults genuinely liking each other was revolutionary. It taught kids that a friend can look like anyone. It broke the "us vs. them" mentality before it could even start. They showed that friendship is a neighborhood, not a clique.
The Science of "Prosocial" Media
There is real data here. The "Sesame Street Effect" is a documented phenomenon. A 2015 study by researchers at Wellesley College and the University of Maryland found that children who watched Sesame Street performed better in school and had higher levels of social competence.

Because the show focuses on "Theory of Mind." That’s a fancy way of saying "the ability to understand that other people have thoughts and feelings different from your own." When Elmo asks, "How does Zoe feel?" he’s teaching empathy. That is the baseline of friendship. Without empathy, you're just two people in the same room.
The Hardest Lessons: Saying Goodbye
Maybe the most profound answer to "what is friend" came in 1983. When Will Lee, the actor who played Mr. Hooper, passed away, the show didn't recast him. They didn't say he moved away. They told Big Bird—and millions of kids—that their friend had died.
It was heartbreaking.
But it defined friendship in its most permanent form: memory. Big Bird struggled to understand why Mr. Hooper wasn't coming back to make him birdseed milkshakes. The adults on the street didn't give him platitudes. They sat with him. They showed that being a friend means supporting someone through grief, even when you don't have all the answers.
Modern Friendships: Julia and Karli
The show keeps evolving because kids' lives keep changing. Recently, we’ve seen the introduction of Julia, a Muppet with autism. Through Julia, the show teaches that being a friend might mean changing how you play. It might mean being a little quieter or understanding why a friend doesn't want to be touched.
Then there’s Karli, a Muppet in foster care whose mother struggles with addiction. These are heavy topics. But they answer the "what is friend" question for kids in the most difficult circumstances. They say: "You are not alone, and I am here for you even when things are scary at home."

What We Get Wrong About Sesame Street
A lot of people think the show is just about "sunshine and rainbows." It’s not. It’s actually pretty gritty sometimes. It’s set in a city. There’s trash. People get cranky. The genius of the show is that it places friendship in a realistic setting.
Friendship isn't a reward for being perfect. It's the safety net for when you're not.
Practical Ways to Apply "The Street" Philosophy
If you want to bring these lessons into the real world, it's actually simpler than you think. You don't need a high-budget puppet or a catchy song. You just need to follow the blueprint they've been laying down for over fifty years.
- Practice "The Pause": When a friend does something annoying, do what the Muppets do. Take a breath. Ask yourself why they might be acting that way. Most of the time, Oscar isn't mean because he hates you; he’s just a Grouch. It’s his nature.
- Acknowledge the Weirdness: Bert and Ernie don't pretend they are the same. They acknowledge their differences constantly. "You're doing that thing again, Ernie." "I know, Bert!" Acceptance starts with noticing, not ignoring.
- Show Up for the Boredom: Some of the best Sesame Street moments are just characters sitting on the stoop doing nothing. Real friendship is being able to be bored together without it being awkward.
- Say the Hard Thing: If you’re hurt, say it. Big Bird is the king of saying, "That made me feel sad." It’s not "uncool" to have feelings. It’s the only way to keep the friendship healthy.
Moving Forward With Your Own "Street"
The question of Sesame Street what is friend isn't one that ever gets a final, single-sentence answer. It's a lifelong curriculum. Whether you're four or forty, the mechanics of being a good person remain remarkably consistent. You listen. You share your cookies (sometimes). You apologize when you mess up.
Stop worrying about being the most popular person in the room. Instead, focus on being the person who makes the room feel safe for someone else.
To take this from theory to practice, start by identifying one "prosocial" habit you've let slip. Maybe it's checking in on a friend who has gone quiet, or maybe it's finally offering that apology you've been holding back. Friendship is a muscle, and like any muscle, it needs a regular workout to stay strong. Go be the person Big Bird thinks you are.
Connect with someone today without an agenda. Ask a genuine question. Listen to the answer without planning what you’re going to say next. That is how the "Street" survives in the real world. That is how you answer the question for yourself.
