What makes a memorable story for you?

[Elfmaster XK]

I think we've had a thread on what makes successful stories (bad as I am I didn't check *hides from mods*), but I was wondering what makes a story trully memorable for you, like the small things that make it beautiful?

I like it when the writer gets the unusual combination of a good ending, that closes off all the main issues within the story, but still leaves you with at least one thing to think about. I hate it when it ends and you are not satisfied, but I do like it if there is perhaps a subtle, unasked question for you to think on.

As a writer myself, and a language student I love beautiful descriptions, and think good description is an art form many have but don't quite get to it because they over or under work it. I always remember the quote "don't tell them the story, show them." If you show someone something then they see what is there in its simplicity.

And with that, a simple but strong story line is always best.

Anyone have any opinions? Or examples of things they loved?
