I've always felt that story codes should represent major elements of a story, not just a passing event. If there is something you feel should be coded, let me know about it and tell me why.
If I agree, I'll add the code.
The one that comes to mind is "tears". I won't code it unless I get mail saying I should. I'm not writing a tear-jerker, but if you feel so moved, let me know.
My favorite story for that is "The Last Wish Blues" by Lubrican. There is one part where you will feel moved, so "tears" is appropriate there. I haven't written anything that would so move me, but that's just me.
