Students brace for emotional return

Students and teachers returned Sunday to a Florida school for the first time since 17 people were shot dead there, consoling each other even as they called for swift action to address gun violence.

"Imagine (being) in a plane crash and then having to get on the same plane every day and fly somewhere else -- it's never going to be the same," David Hogg, a survivor of the February 14 shooting at a Parkland, Florida high school, told ABC television's "This Week."

The school held a voluntary "orientation" Sunday, with teachers and staff due back starting yesterday and classes resuming on Wednesday -- a prospect described as "daunting" and "scary," but which is also a step for survivors to move forward after the attack.

One teacher who had already been back told NPR radio that the shock of returning to a classroom left exactly as it had been during the carnage -- notebooks still on desks, the calendar still set to February 14 -- made her so physically ill she had to leave.

But Cameron Kasky, a student who survived the slaughter, tweeted a picture of people on campus, saying: "It is GOOD TO BE HOME."
