"It will never be forgotten. One of the deceased learners was a friend to one of my sons. They were close and my son can't stop speaking about the deceased learner."I am grateful that none of my children were injured. Unfortunately, what hurts me is that innocent and young lives have been lost. As parents, we are supporting the bereaved families to ensure that they are healed emotionally. We also pray for those in hospital for a speedy recovery," she said. Rescue effortsMatankiso Meraka also accompanied her nephew to the school for counselling on Tuesday. Meraka said her nephew was close to three of the deceased pupils and that they played sport and represented the school together in various competitions."Since Friday, my nephew is quiet and doesn't talk a lot. I am worried that he is bottling this thing inside. I want him to be counselled to quickly heal and begin his studies. For now, he doesn't look like he is ready to continue with his studies. He has stopped talking and is always alone," she said.Her nephew was among many who assisted with the rescue efforts on Friday to free those who were trapped under the rubble."The things he [said] he saw when he rescued learners who were trapped are scary. I am not going to divulge the type of injuries those learners suffered when the concrete slab collapsed on them," Meraka said.
