Hillary Rodham Clinton is the guest-editor of our Volume IV issue, on newsstands nationally December 5. She gave the keynote address at the first-ever Teen Vogue Summit in conversation with actress, scholar, and activist Yara Shahidi. The Teen Vogue Summit took place on December 1 & 2 in Los Angeles. Relive some moments here.

She was the teacher’s favorite. I was the troublemaker. Just look at our class photo: Hillary at one end with Mrs. King’s hand on her shoulder; me on the other with a mischievous look in my eye. Hillary Diane Rodham Clinton has been my best friend since I was 11 and she was almost 11 (she loves those six months when she gets to say she’s a year younger!). Having left my Chicago friends behind, I was the new girl in sixth grade at Eugene Field School in Park Ridge, Illinois. We hit it off right away. We loved to ice-skate, ride our bikes, and listen to records. We lived for the Beatles. She favored Paul, and I liked George. When he died in 2001, she called me to offer condolences. We both loved books, especially Nancy Drew mysteries. To this day, we exchange reading lists.

Over the years, we’ve shared hearing Dr. Martin Luther King Jr. speak in Chicago, being “Goldwater Girls,” and attending the 1968 Democratic National Convention. Together, we made that big turn from Republican to Democrat and never looked back. We’ve been there for each other’s weddings, celebrated the births of our babies, and welcomed grandchildren — that’s been the very best of all!

Hard workers don’t always get a lot of credit, especially hardworking women.

Hillary is loyal, caring, and honest. Every time we talk, we pick up where we left off, as if no time has passed. She laughs with gusto and likes her food spicy. I can’t help but take it personally when people attack my friend. If they could just meet her, they would understand what makes her so special. I’ll never forget when I had lunch with her in the Senate dining room after she’d been elected senator. All these Republicans who had spent years criticizing her kept coming up to me, saying, “She works really hard! Do you know how hard she works?!” That meant the world to me. Hard workers don’t always get a lot of credit, especially hardworking women.

One of the most incredible moments of my life occurred at the 2016 Democratic National Convention when I got to cast Illinois’s votes during the roll call. Our delegation had been waiting for our turn when someone said, “OK, we’re next!” That’s when it hit me. I felt her parents’ presence in the room. I kept imagining the two of us as sixth graders, never believing the country would nominate a woman for president, let alone one of us! I pulled myself together and said, “This one’s for you, Hill!”

We’ve also supported each other through hard times, loss, and sorrow, including the months after the election. Hillary would have been a wonderful president — for our children, our grandchildren, the world. She would have led this country with grace, wisdom, and dedication. Instead, she’s showing us the depth of her resilience and her commitment to doing good. My greatest wish for every young person is a friend who can travel the world, change the course of history, and still be there for you through thick and thin. Your very own Hillary.
