If, after hanging out with someone you feel worn out and depleted, that person is a vampire. If, after hanging out with someone you still feel full of energy, that person is not a vampire. Of course, The Vampire Test works on many things in our lives, not just people—you can apply it to jobs, hobbies, places, etc. Vampires cannot be cured. Should you find yourself in the presence of a vampire, be like Brancusi, and banish it from your life forever.
