Other than being respectful, what are the bare minimums or non-negotiable qualities that someone has to have in order for you to go out with them?

I know respect is obvious, and for instance sometimes people say that being respectful and nice is enough, and sometimes people say that nice by itself isn't nearly enough to want to date someone. So what are your personal non negotiable qualities that someone must have if they are going to be with you, and be able to keep you happy?
