We are not brothers;
but some think that we are.
We followed a man no one could see.
But whom we can feel.
They did not understand us.
So they chose to get rid of us.
They placed us in a ring of fire.
Three went in,
four stood in the fire talking,
but only three came out.
Without a single scar.
Who are we?
