It's cool you remember your stories. I forget in a flash, if I haven't put it down.
I don't think any story is new under the sun. They've all been done already, in some form, and I think a lot of writers actually get themselves caught in this folly of trying to create something that hasn't been done before. 100% new? Sounds impossible.
I think it was Hemingway who said you need to learn and read, because the stories have been done already. You just need to figure out what's been done, and how you can do it better (aka in a way we ain't seen before) ;)
Cool post.
