If you've grown up in rural S. Sudan, you may have no concept whatsoever of c-o-l-d, as the weather there is equatorially hot year-round (either hot and dusty dry, or hot and rainy wet). The electricity needed to produce refrigeration would be extremely rare. In fact, in the brief workshop that refugees from Sudan have before being resettled out of refugee camps to begin a new life in Europe or America, the teachers sometimes pass a large chunk of ice around the classroom. "This is cold," they say. "You may live in a place that feels like this."
Sr Edvine, Principal of St Bakhita Primary School, spent an overnight in Lake Tahoe while visiting California during March. The area had already recorded 59 feet of winter snow (yes, feet!). Edvine sat bundled inside the house, close to a roaring fireplace. Now she'll be able to describe c-o-l-d to her students in South Sudan!
