And what did you think the first time you saw the HP/SS pairing? Intrigued? Skeptical?
Actually, I searched for it myself after I'd stumbled on HP fanfiction (which was het) for the fist time and before I even knew what slash was. I wondered, "Could people be writing male/male pairings as well? Let's try to look for, oh, Snape/Harry - or Snape/Sirius." And that's how I found my first Snarry and devoured it gleefully. ;) It was a novel-length story riddled with typos and awful characterisation that today would make me hit the back button at once, but at the time I thought it was the best thing ever.
