The hell? Usually, if someone IMs me, I know who he or she is. And even if I've never actually interacted with her ('cause it is usually a her), I've run across her on some kind of fandom group, or she's like a friend of a friend. Not this time. The guy didn't even know the fandoms in which I was involved.
So, yeah. If you're going to randomly talk to me, try not to make your first question "Do you write femslash?" 'Cause if I don't know you? A bit freaky.
