Thanks to those who posted comments, emailed me and called me on my previous post. It's a good thing to hear people's opinions, and more importantly, to help me feel like I did the right thing years ago by taking my friendship from someone who didn't deserve it.
As far as what I did: well, because my curiosity will always get the best of me, I accepted the friend request, then I searched her page for details of what had been going on. Finding nothing and feeling pretty satisfied, I deleted her as my friend a few minutes later. No harm, no foul, and of course, my curiosity is satisfied and I know she's not all in my page, finding out what's been going on in my life.
And, now, onto more important things - like baking cookies!
