Huh. I just now noticed that somebody who unfriended me lo-these-many-months-if-not-years-ago not only unfriended me, they deleted one or more (haven't bothered to check, past the one where I noticed it) comments they'd left on my LJ. The one I noticed was a totally innocuous comment, along the lines of "I never seem to hear about interesting local stuff — how'd you hear about this?"
These days, and at the current state of my practice, I'm in a place of not erasing public stuff. Did I post that in the past, even if it's something I disagree with now, or related to somebody I no longer wish to associate with? Well, that's where I was and who I was associating with and what I was thinking at the time.
If my past actions, opinions, and associations are enough to make you want to repudiate me… Well, okay. Bye! Not quite sure I'm awakened enough to say "been nice knowing you", but I don't wish you ill.
