MONROE, Connecticut (NBC NEWS) -- It's been another difficult and emotional day in Newtown, Connecticut.
For the first time since the deadly shooting spree at Sandy Hook Elementary students and teachers who survived the attack were back in class.
Many arrived at their new campus, seven miles away in the town of Monroe, by bus.
"The kids all got off the bus, a lot of them were happy to see their friends they hadn't seen in a while. They're excited about the new school," said Monroe Police Lt. Keith White.
"It's hard to imagine the kids being there, but also the teachers being there in that incident, what that's doing to them psychologically," said father Andrew Paley.
Even harder to understand is what it might take to move on.
Counselors and administrators say an important part of that process came Thursday as students returned to the structure and routine of the classroom under the watchful eyes of a heavy police presence in and around the school.
