Millie Bobby Brown may have recently left Twitter after being bullied on the social media platform, but the Stranger Things breakout star still has plenty to say to those trying to tear her down. In a video acceptance speech shared at the MTV Movie & TV Awards on Monday night—Brown was not able to attend in person due to an injury that kept her in Atlanta—the young actor shared some wisdom that anyone can get down with. “Finally, since I know there are many young people watching this—and even to the adults, too—they could probably use the reminder that I was taught: If you don’t have anything nice to say, just don’t say it,” she reminded the audience.
