Feb 18, 2018; Parkland, FL, USA; Emma Gonz·lez, 18, a senior at Marjory Stoneman Douglas High School poses for a photo at North Community Park. Gonz·lez became a viral sensation after videos of her impassioned speech at an anti-gun rally in Fort Lauderdale flooded social media. Now, she is helping to lead the #NeverAgain movement with her fellow classmates. "Itís funny. I didnít even have a Twitter account before two hours ago and it was trending on Twitter all day yesterday," Gonz·lez said. "I have become somewhat of a spokesperson for this, but weíre all saying the same thing. That's why we teamed up together like this because we know each other, we love each other very much and we all agree on the same stuff. Weíre happy that all of us are still alive and weíre gonna make sure it stays that way for the people in our neighboring communities. For our neighbors, our cousins, this generation, not the next generation because the next generation will never have to worry about this because of us."
