<human>: Wow, the title makes me sound horrible.  Anyway, the backstory is that we were really close friends for about three years, back in high school times.  Of course, college happened - we went to entirely different schools, had entirely different experiences, and became different people.  Over the years, we just naturally drifted and haven't really spoken in five years.  We were still friends on FB and Twitter, but there was no interaction there.

Recently she has made repeated attempts to get in touch with me via FB and Twitter, asking what I'm up to and randomly referencing old inside jokes.  I've basically blown these off.  I'm not super-active on either site (no FB posts since June wooo), so it's plausible that I just haven't logged in.  

But of course, I have seen them, and I have no interest in responding.  Like I said, we've both changed a lot since HS - she's become a much more spiritual and relentlessly (obnoxiously, in my opinion) positive person.  And I support that; she's made a lot of really good changes in her life and I'm happy for her.  But if her status updates annoy the shit out of me, I definitely have no desire to start up a superficial catch-up conversation.  I already know everything she does cause she updates all the goddamn time; I choose not to do so, and now she wants to know all about my life all of a sudden.

I know I should feel horrible for ignoring an old friend, but quite honestly... I just don't care.  It's been five years since we had a real conversation and it's not a friendship I really want to rekindle.  Our personalities have shifted in entirely opposite directions.  I'm totally fine with the fadeout (which we've already done for FIVE YEARS), but she won't stop messaging me now.  I almost want to unfriend her, but that feels really bitchy.

Can you condense the text into a few key points?
<bot>: Old friend wants to reconnect; I have absolutely no interest in doing so.  How do I handle this without being a supreme bitch?
