Never say anything about a person you wouldn't say to them directly, and don't try people without accusing them to their face. Badmouthing people behind their backs shows a serious lack of integrity and is counterproductive. It doesn't yield any beneficial change, and it subverts both the people you are badmouthing and the environment as a whole.
You've got the people you know, which are problematic. Always. They're rich but they're also real people living their lives alongside you. Then you've got the people that you make-up completely, who are often missing a dimension if they don't have some reference to real people. So strangers exist in this in-between space, where in not knowing them, you are creating a fiction for them, even in passing, but at the same time, there they are, with their actual bodies and their actual clothes. It's totally enticing.
