One of my friend shared a way to find out a list of people that facebook thinks they are your closest friend.
Not that I believe it was true
however, the result was a little unexpected.
I have all the reasons to suspect how accurate it was
but something about it confuses me(and I'm not telling you what ;P)
Anyway,my lession is
don't be a creep, know people by interacting with them if you do care about them.
Eeven though I learned from game theory class,
information is power,
but doing it to ones you care is too cruel
both to yourself and others
