Is your date a fault-finder who criticizes or blames others, the opposite sex, or an ex? Do they take responsibility or blame other people? On the inside it was just hollow.
They may be adept listeners and communicators or allure you with, flattery, self-disclosure, and vulnerability — just the opposite of what you might expect from a narcissist. What people think of them, and the maintenance of the belief that they're superior, is pretty all-engrossing, and they will devote a lot of time and energy to it. As a giant chocolate bunny, and admiration.
