軍官與紳士

HBO is broadcasting "An Officer & a Gentleman (軍官與紳士)"
The Internet Movie Database

Falling in love with an aviator ~
woo~ what a romantic experience ....
the summary plotted that :
"Zack Mayo is a loner who has never had to rely on anyone but himself."
Zack: NO! I do wanna anyone love me !!!
and...
"...their training officer, Gunnery Sergeant Emil Foley
who teaches Zack a lesson in the importance of relying on your friends and colleagues."

I'm pondering over the matter...
which one is better ?
'never rely on anyone ' or 'relying on your friends' ?
obviously, the latter could make your life easy !
but...
k k ....
We all have that "rebellious nature" ~~~~

by the way...
why the title is "A Officer and A Gentleman" ?
this is a romantic story !!!!
so .... don't you think "A Lady and A Gentleman" or something is more suitable than this? ^^a
