Amazing, thanks for the link. I actually thought (being a newbie writer to this stuff mind you) they were one in the same in context to they both had a choice to say no, and not taken as a "yes", or dealbreaker. I could have misread something here, but this did help a bit to learn more on the subject, and for my fan fic I am working on this does indeed help.
Yet I still am tending to think the main of my fan fic (main s) will still fall under the latter category, but as I said.. thanks for sharing the link, I shall bookmark and revisit it at times,
Now time to do more research on the subject. Have fun all.
