Why are strangers nicer then the ones you're familiar with?

The ones you grow up with,
Go to school with,
Become friends with.  

Why is it easier to talk to strangers then the ones you know personally?

The ones who know you,
See you every day,
Talk to you face-to-face.

What is the appeal that will make a stranger on the Internet more comforting then friends?

The ones who love you,
Befriend you,
Are physically there for you.

I know why. Possibly better then anyone.

Because in being anonymous, there's secrecy.

And in secrecy we trust.
