Same here. Though I really do not need to 'ship'. I can adore a show without a romantic plot.

Not only do boundaries keep things meaningful but they keep them a creation. When giving it to the audience to watch or to read, the author agrees they are going to make the story and the characters theirs. Yet if you push too far, you just rewrite and it is not his work -it is an hommage, a spin-off, a fanfic, not the original show or book. It is your creation.
