J.K. Rowling is one bad ass muggle (but let’s face it, she’s one bad ass witch).

It’s hard to believe it’s been 20 years since the release of the first book: Harry Potter and the Philosopher’s Stone. In a tweet, the renowned author thanked her legions of fans.

“Twenty years ago today, a world that I had lived in alone was suddenly open to others. It’s been wonderful. Thank you,” she wrote.

She also included a new hashtag #HarryPotter20, which turns into a Harry Potter emoji (a lightning bold and round glasses).

J.K., from all of us to you, trust me when I say it’s YOU we should be thanking. Thanks for the memories!

Oh, and keep on tweeting!
