Friend and Enemy

Logical thinking:

1. The friend of our friend is our friend! (positive and positive is positive)
2. The friend of our enemy is our enemy! (positive and negative is negative)
3. The enemy of our friend is our enemy! (negative and positive is negative)
4. The enemy of our enemy is our friend! (negative and negative become positive)

Human is too complicated:

1. The friend of our friend is sometime our enemy!
2. The friend of our enemy is sometime our friend!
3. The enemy of our friend is sometime our friend too!
4. The enemy of our enemy is sometime also our enemy!

So what to do? Perhaps Cruelness and ruthless is one of the solution to this? When you have no friend, you do not have enemy! Everyone is potentially your friend and thus everyone is potentially your enemy.
