“…So really, it's just y—" [enemy player kills him] "—oh, dammit!—you, your gun, and your friends.”

“Is it a gun, is it a knife?
Is it a wallet, this is your life?
It ain't no secret,
It ain't no secret,
No secret my friend.
You can get killed just for living
In your American skin.”

“Your enemy is never a villain in his own eyes. Keep this in mind; it may offer a way to make him your friend. If not, you can kill him without hate — and quickly.”

“Keep your enemies close, but your friends closer. That way your friends are between you and your enemies.”

“A good friend will help you plant your tulips. A great friend will help you plant a gun on the unarmed intruder you just shot.”

“If you want enemies, excel your friends; but if you want friends, let your friends excel you.”

“Your hands on a gun butt right now, isn't it? Afraid of me?”
“Just want to make sure I can take care of you.”
“Oh, really?”
“Yeah, in case you need Glock-to-mouth-resuscitation.”

“If this is how you treat your friends, no wonder you have so many enemies.”

“Your Worst Enemy Could Be Your Best Friend && Your Best Friend Your Worst Enemy”

“If you have an enemy, then learn and know your enemy, don't just be mad at him or her”
