Alright gents I got some interesting stuff...
A girl I've never heard of, ever, sends me a friend request on a mostly private social networking account I have on a relatively large site that people of my age visit frequently (...) I don't add a lot of people as friends and so this kinda came at me as a surprise. I have no remembrance of ever meeting her... in fact I'm almost positive we've never crossed paths at all.
I could see her profile in full however so I took it upon myself to figure more out. She's from my hometown but her rather alarming age (or lack thereof) means we didn't go to high school together.
The biggest link I can see between us is that she is in some of the wedding photos of this girl I used to know really well. She also has in her friend list the girl I've talked about ever-so-often this year, along with some other random old friends from high school, none of which I ever talk to.
No note attached to the friend request. But since she's vain enough to post pictures on her public profile I see no harm in posting one here:
I feel like this is some sort of trap.
