Between serving as a Supreme Court Justice, moonlighting as an actor, and collecting jabots (a.k.a. the fancy collars judges wear), Ruth Bader Ginsburg has a pretty busy schedule. But as The Huffington Post reports, The Notorious RBG still managed to find the time to write a personalized letter to an 8-year-old girl in the Washington, D.C. area, who dressed up like her for her school’s “Superhero Day.”

Inspired by I Dissent, an illustrated children’s book chronicling Ginsburg’s life and career, Michele Threefoot donned a judicial-inspired getup and a pair of large-framed glasses last December to pay homage to the Supreme Court’s second female justice. Her mother, Krista Wujek Threefoot, posted a picture of Michele’s ensemble in Pantsuit Nation, the pro-Hillary Clinton Facebook group, and added text to the picture: “Yes, world. Girls who read are dangerous” (inspired by the quote “A well-read woman is a dangerous creature,” coined by author Lisa Kleypas).

The picture went viral, and Ginsburg herself caught wind of Michele’s unconventional superhero costume. RBG’s assistant contacted Threefoot, asking for her address, and shortly after, the Supreme Court justice’s mini doppelgänger received a handwritten note from her hero.

It read: “Dear Michele: You look just like me! May you continue to thrive on reading and learning. Every good wish, Ruth Bader Ginsburg.”

According to Threefoot, Michele was “super duper excited!” to hear from RBG herself. “When I read it, I felt really happy because she said I looked just like her. It was really special because she wrote it by hand,” Michele told her mom (as quoted by HuffPost).

To inspire Michele to keep reading, the letter also contained the following quote: “Reading is the key that opens doors to many good things in life. Reading shaped my dreams, and more reading helped me make my dreams come true.”

Michele plans to write a thank-you note to Ginsburg. She also took her prized piece of correspondence to school—and now, several of her classmates reportedly want to dress up like real-life inspirational figures next year, including Bill Gates and Hillary Clinton.
