They are, you might know

They might be drunk
They might be had the joyless eyes
But they know the rules
They might be my secret admirer
They might be my secret enemy
But they are my friends
They might be uncool
They might be old school
But they are polite
They are my friends
They are my friends
They know you
They appreciate you as their friends
They never stab you
They never slap you
They know the rules
They never flirt on me
And I won't flirt on them
They might be robber
They might be murderer
But they won't rob or kill you
They know the rules, how to make you as their friends
They pleasure to know you
