Guess Who - Equations: Friend Or Enemy

It was easy at the beginning
But got complicated in the evening
The friend of a friend is a friend
The enemy of an enemy is a friend
The friend of an enemy is an enemy
The enemy of the friend is an enemy
But what if it's wrapped up
And the only fact is that you give up
If The friend of the enemy is your friend
The enemy of your friend is the enemy of your enemy
The friend of your friend is also an enemy
The enemy of your friend is the friend of a friend
What if the enemy of the enemy is an enemy of a friend
The friend is the enemy of another friend
The enemy is the friend of your friend
The enemy of your friend is the enemy of your enemy
And the best phrase of it all
Was the one that signed my fall
What if the enemy of an enemy is an enemy of an enemy? ? ? ? ?

It's all getting complicated by noon
I think I'll black out very soon
Friendship is something we show
It was never an equation we should know
