As groups of students from across the United States participated in the National School Walkout, one 7-year-old stood alone at her elementary school in protest of continued violence in schools.

Havana Chapman-Edwards, a 7-year-old student from Washington, D.C., was the only one at her school to walk out of classes on Friday, April 20. She posted an image from her protest on Twitter, writing: "I am all alone at my school, but I know I am not alone."

In an interview with Teen Vogue, Havana shared that she had urged her other classmates to join her and was sad that they didn't. "I didn't understand why they didn't care," she said. "I tried to tell them to come, but they said no." Teen Vogue has reached out to Havana's school for comment.

Havana is still hopeful that the next walkout will be different. "After watching her sit in silence to honor the Columbine students, we turned on CNN to watch the walkouts at other schools," her mother, Bethany Edwards, tells Teen Vogue. "She said, 'I am going to tell my friends I did this, and then next time there will be more of us. That means we are winning.' I knew then that she understood what it means to be a leader, even in the most simple terms."

After attending the March for Our Lives on March 24, Havana knew that she wanted to do more to help end gun violence in schools. She says she's been closely following the Twitter accounts of students from Parkland, Florida, and credits Emma González and Naomi Wadler with inspiring her. While Havana acknowledged that she isn't yet old enough to vote, she doesn't want age to stand in the way of her activism. "I want to help the big kids and adults and show them I support them as much as I can until I am old enough to vote," she tells Teen Vogue.

For today's walkout, Havana chose to wear an astronaut suit. Bethany explained the significance of the outfit, telling Teen Vogue: "Havana wants to be an astronaut when she grows up, so she wore her astronaut suit to show her friends and the world that little black girls have dreams and aspirations and they are strong and beautiful and deserve the same chance to achieve their goals as everyone else."

Havana admits that her friends don't really talk about the violence happening in schools, but she has open conversations with her parents. "We talk about how all kids should be treated equally," she said. "All kids deserve to grow up and have their dream job." Bethany also said that the family has touched on the impact of past school shootings, including Columbine and Sandy Hook. "It's not a topic we wanted to or even had the option to shield her from," Bethany said.

Although Havana may have stood alone today, she's already started planning for the future. She previously started a book club, which was sparked in part because of her activism with the Black Lives Matter movement. "I believe Black Books Matter, too, and I donate a lot of books to my school with black girls in them," she explains.

She is also prepared to encourage other students to stand up for what they believe in. "You are never too little to make a difference," Havana said. "I know that just because I am only seven doesn't mean that I can't help other people every day. My advice to other kids is that you don't have to be a grownup or be famous to change the world. Sometimes you just have to choose kind to change the world."
