There are plenty of people who have literally thousands of Facebook friends. And they can't possibly know them all. And with Twitter, there's no telling who's following your every move.
Some of these people may not exactly have your best interests in mind ... and with friends like those ... Who needs enemies?
That's a page from my notebook.
