Child always have something to teach "Just wear a helmet. A rocket just started". They knows how to recognize the lighting and the noise of the reactors and how to make dynamite sticks as well as their toys. "Day and night in the mines, the dust is always present. It clouds the vision. Takes over our lives. You born as a miner, you give birth to miners, and you die as a miner. In the dust."
