Rubbing two sticks together to make a fire: NONSENSE

There are many ways to start a fire: a bowdrill, a hand drill, friction by rubbing a specially made stick against a groove cut into a seasoned piece of wood to create a coal, rubbing rope to create a coal, steelwool and a battery, a flint and steel and charcloth, a flint and steel and orange oil ignition, flint and steel and charred punkwood, a fresnel lens, a magifying lens from ice, a bit of chocolate to polish a can into a lens to create fire, etc

THERE IS NO WAY to rub sticks against each other to make a fire. At best you could possibly make a coal. The stuff people say makes me laugh hysterically....

It's either that or decide to quit trying to teach at all.
