Armed Forces Recruitment Day
Albuquerque High School, 1962
After the Navy,
the Air Force, and
the Army,
Sgt. Castillo,
the Marine Corps
recruiter,
got a standing ovation
when he walked up
to the microphone
and said proudly
that unlike
the rest, all
he could promise
was a pack,
a rifle, and
a damned hard time.
Except for that,
he was the biggest
of liars.
