She was afraid of what it would feel like, but she needed to know, so Melissa Falkowski pulled into the faculty parking lot. She took a deep breath in through her nose and climbed out of her car. She was back, in front of Marjory Stoneman Douglas High School.

It had been a week and a day since the language-arts teacher had hidden with her students in her classroom closet while a gunman killed 17 people with an AR-15 rifle. Melissa, 35, had often said that she spent more time in her classroom than at her own house; that Douglas, where she had taught for 14 years, was home. Now, as she walked toward the entrance, she wondered if she knew where she was at all.

On Thursday, Feb. 22, 2018, Melissa Falkowski, 35, an English, journalism and creative writing teacher at Marjory Stoneman Douglas High School, looks inside her classroom's closet where she hid with 19 students during the mass shooting that occurred on Wednesday, Feb. 14, 2018, at the school in Parkland, Fla. Today was the first time Falkowski returned to her classroom since that day. ALESSANDRA DA PRA | Times
