starting a fire with two stones is an art
you can’t use just any two stones for a start
I wonder how man first figured this out
how did such discoveries come about?
was someone sitting cold and bored in a Belgian cave
with nothing better to do than misbehave
and strike some flint and iron pyrite together
near some tender that just happened to be there
starting a smoky fire that got him kicked out
until they realized it was something to write about?
