I had an event today that made me think I need to revise my friend-ing policy. Sometime over this weekend, I am going to defriend anyone who has not mutually friended me, with a couple of exceptions related to people who do good fic recs.
Really, it's not you, it's me. So if you find that I defriended you, and you want me to re-friend you, all you have to do is friend me. LJ notifies me of people friending me, and I will friend you back and all will be well.
And it follows that in the future, if I note that if someone has unfriended me, I will probably mutually unfriend.
This relates to the fact that I cannot keep my mouth shut and am a terrible busybody and it is much better if I don't make comments in the journals of people who don't really know me. Plus, I tend to become irrationally concerned about the people on my friends page as if they were real people in my real life, and getting rid of people who don't know who the hell I am is probably good for me psychologically.
Like I said! It's not you, it's me.
