With a short story, you tend to just have one problem to solve.
The best way to discuss this though, would be to throw up some short story examples.
We kind of did that with TJ's story, but I still find it difficult to detect that structure in everything I read. Honestly, I'm not sure it works for me to think about it in such a prescriptive way. Everyone approaches these things differently, though. And maybe if I get serious about being published I'll need to change my mind!
