Your icon does look awfully familiar. I think I may have read some of your fic, but my memory is terrible on such things.
Hm, I can't remember whether you commented on one of my fics, so I can't tell you which one it was... But I use this icon quite often so maybe you've just seen it somewhere else.

(*pokes our brains* we should really do some memory-training or however these things are called *g*)
