What does this button do?

I was just pushing buttons to see what would happen. I pushed the Friend button on my profile page and I got an error message informing me very sternly that "you cannot be friends with yourself!!"

With two exclamation points.

I thought that was an interesting bit of philosophy. Sort of like the whole 'your greatest enemy/critic is yourself' thing.

We here at marapets apparently aren't at peace with ourselves.
