|Joyce & Pontino switching on the lights at home|
No sooner had Joyce (36) and Pontino (44) flicked on the lights, than brightness filled their house. Their faces beamed with delight. They could not hide their joy. They giggled. There seems to be nothing special about switching on a light bulb unless you are a small scale farmer living in a rural village in eastern Zambia and your house has just been connected to the national grid.
