(AP) — Nearly three months after a twister blasted through Moore, Okla., and destroyed two elementary schools, students are going back to class.

And although many families are ready to return to a familiar routine, parents and teachers say many children in the Oklahoma City suburb have fears that are still fresh and a lot more healing to do.

One young girl is so afraid of the wind that she carries headphones to block out the noise. Other kids are traumatized by memories of their narrow escape and friends who died just a few feet away from them.

Classes resume Friday in temporary buildings until Plaza Towers Elementary and Briarwood Elementary are rebuilt. The May 20 tornado killed 24 people and wrecked scores of homes and businesses.
