hmmm, you know what. I never really understood the idea of making your diary friends only. I mean it's an internet diary. If you don't want people to read something, don't worite it!
But I think I've figured it out. It's to tell people that could previously read it that you don't want to be friends with them anymore. Very subtle. The diary is friends only any they are no longer a friend. I get it now.
