Oh, I wish I could write this way, but it doesn't come at all naturally to me. When I try to write spare it gets boring because I don't have that narrative intuition about which precise words and exactly how to pitch the tempo and details. I suck at humor, too. If only I could sit at your feet and learn.
Flexibility and imagination? Not stupid. Quite the opposite! Good. Very, very good! There's a kind of joy in seeing someone take a cracktastic idea and pull it off with such elegance and affection. Besides, Snarry's so far outside the canon box already that stretching . . the two of them . . a little farther . . is pretty much irresistible. ;)
Cross-dressing! *headsmack* Of course! And appropos of nothing except that reading your comment on their age difference probably brought it to mind, I just remembered a kink I neglected to mention so I'll propagandize for it here. It would be wicked cool to see more Snarry Severitus. Because it is *so* wrong. Just wrong. And crossdressing Snarry Severitus? *drools* OMFG.
So if you ever run out of ideas *snorts at self* and are casting around for inspiration, well . . . *waves pom poms frantically*
