An old classmate tracked me down a couple of months ago, and we spent some time chatting on Facebook. I had to come out to her at the time because I've transitioned on FB... but as she's a South African of a certain generation, her awareness of LGBT issues is pretty much stuck in the 1980s.

So she's asked a lot of inappropriate questions about my transition, and as we were good friends growing up I decided to answer some of them, even if it felt uncomfortable to do so. But now she keeps pestering me on FB.
Every time I show up as being online on FB she tries to chat... and she keeps pushing to see current photos, presumably so she can get her Jerry Springer thrills. I'm not inclined to help her out with that.
So basically, I'm spooked off of Facebook because an old friend is making me feel uncomfortable with her intrusive, inappropriate questions and her constant badgering to see 'before & after' photos.
