You must be prepared to lose touch often and accept all. For real Vampires accept human friendships on their terms only. Unless you understand and accept these terms as well, you will not be happy as the friend of a Vampire. This is true. If you wish to know about the Inheritors, re-read Classicals.
Inheritors ARE Classicals without being transformed and infected.
Remember everyone, we are doing our best to keep things real here and separate fact from lie, propaganda, fiction, legend and fantasy. It is not fun for most Real Vampires. It means years and years of loneliness, watching the few you do love die. Over and over again. And since they live longer, Vampires must endure this loss many more times than the normal human, if they are prone to human friendships.
