One Monday afternoon in May 2013, Diana Palmore was at home with her husband, Pete, when they heard    a tornado coming the town. Diana’s daughter Monica was at the local school and Diana decided to go and pick her before the tornado reached the town. She ran as fast as she could to the school. In her classroom, Monica and her classmates were sitting under their desks. Diana ran in and took Monica. But the tornado was much closer now and it was too dangerous to go outside, so they hid in a bathroom. When the tornado hit, it ripped the roof from the school. Monica and Diana looked up and saw cars and trees flying above the school. ‘It was very scary. The whole school was shaking,’ said Monica.

When the storm passed, Monica and her mum went home but it was in ruins. They couldn’t find Pete. But they could hear him shouting for help. Then they saw his hand in a cupboard under the stairs. He couldn’t breathe, so they had to get him out quickly. Moments after they pulled him out, the whole house collapsed. The family survived a horrible experience with only small injuries. What a lucky escape!

There were three members in Diana’s family.            ___________
