Friends of Friends

On Facebook, there is a page on Privacy Settings, and you can control who can see what you share.
You are supposed to select one from the following list:
Everyone, Friends of Friends, Friends only, Other.

Personally, I don’t like to be faced with the following “political” situation, but it is off-topic.
“The enemy of my enemy is my friend”
The enemy of my enemy is my friend - Wikipedia The enemy of my enemy is my friend - Wikipedia

The following is also off-topic.
Two’s company, three’s a crowd.

I remember Mori Ougai wrote somewhere that friends-turned enemies are the most dangerous.
