The person that wrote that secret doesn't make any sense. Many people who write stories become attached to their characters. I think that a good writer WILL get attached to their characters. Who are they to judge what a "sad obsession" is, when they cried over a character that isn't even theirs?

I know plenty of people who say fuck for every other word in a sentence. They don't do it to show that they are ~badass~, it's more like a force of habit.
