Friends on Facebook, how does it work?

[Bumph]

On the most update mobile version of Facebook if you click on the about part of someone's profile and scroll down it gives you number of mutual friends and then below that are 4 friends listed.. What is the significance of those 4 people? Is it people you look at? Or people who look at your profile? Or interact with?

The four are usually an example of people that person is friends with, if you have mutual friends with that person it will show some of them. Facebook doesn't choose them based on your interactions with them or their interactions with you.

No Mutual Friends Has Nothing to Do With any of that Mutual Friends are Only Friends That you Have In Common With Between One Person
