He is a fireman.
He puts it all on the line when the bell rings.
A fireman is at once the most fortunate and the least fortunate of men.
He is a man who saves lives because he has seen too much death.
He is a gentle man because he has seen the awesome power of violence out of control.
He is responsive to a child's laughter because his arms have held too many small bodies that will never laugh again.
He is a man who appreciates the simple pleasures of life - hot coffee held in numb, unbending fingers - a warm bed for bone and muscle compelled beyond feeling - the camaraderie of brave men - the divine peace and selfless service of a job well done in the name of all men.
He doesn't wear buttons or wave flags or shout obscenities.
When he marches, it is to honor a fallen comrade.
He doesn't preach the brotherhood of man.
He lives it.
