I love 'Duck Duck Goose' and I hate it, too. As a story it's had me in all states of emotion, yet as a writer I know I could never write anything similar. That kind of length would get me twisted up in knots so fast I'd have to admit myself to the loony bin.
But why? That's what's bothering me. Why can I only seem to write short stories?
I have a couple of nearly finished novels, and yet every time I think of finishing them, I get into a cold sweat.
Know thyself is good advice. I obviously don't.
I've finished 'Bathtime', a short (how did you guess?).
