The Satanic bible Not all vampires suck blood Pt2 br br 'Their sins are not of commission, but of omission. It's what they don't say, not what they do br say, that makes you feel you must account to them. They are much too crafty to make overt br demands upon you, because they know you would resent it, and would have a tangible and br legitimate reason for denying them. br A large percentage of these people have special "attributes" which make their dependence br upon you more feasible and much more effective. Many psychic vampires are invalids (or br pretend to be) or are "mentally or emotionally disturbed." Others might feign ignorance or br incompetence so you will, out of pity - or more often, exasperation - do things for them.
