Heh! I don't know that I planned it, but I'm always happy when philosophizing springs from something I've written! I do a lot of thinking about the characters and the way they relate to one another, even for just a tiny drabble, so I'm thrilled when somebody else wants to talk about it, too.
It's true about length, though! I actually find that I have to work harder when I write short pieces, to try for maximum word-to-impact ratio. Everything has to count, and there's no room for throwaway ideas.
