It could be in your dissertation, a short story you did years ago, even a memo. Literally any bit of writing you've ever done - anything from your hand. For me, it would have to be: "Malfoy doesn't love." "No," She smiles. "I imagine he doesn't." I was a bit drunk and it was high time I went to sleep, but it just...hit me. Out of context, it seems...most wouldn't understand, I reckon. But she's saying that 'Draco' and 'Malfoy' are two different people. Not literally, of course, but figuratively. The 'Malfoy' persona is, well, someone who doesn't love, who's cruel and inhuman. Draco, on the other hand, is the person who loves. So, how about you?
