Drabble challenge!

Who wants drabbles? I feel 'all revved up with no place to go' in terms of writing, right now - I want to do it, but I'm a bit vague as to what I'd actually write... anyway, comment with a drabble request for me, if you please. That way, I get to exercise my writing muscles, and you get drabbles. Everybody wins!

Available fandoms:

- The Lord of the Rings
- The Silmarillion/Unfinished Tales/Children of Hurin
- Harry Potter
- Discworld
- Firefly/Serenity
- Doctor Who - but I've only seen the episodes up to 'Human Nature' in series three, so please, no spoilers.

Happy ficcing!
