Clancy gazed at her for a long moment then turned away as he thought. When he felt he had the right words, he turned back. "It is an interesting question you pose, but it does not have much to do with vampires." He moved to sit on the edge of the bed. "There are many, many children your age - though you are no longer technically a child - and younger who ask the exact same question. Most of them are moved constantly due to their parents' choices. Usually for what ever job or career they pursue, such as the military for one example. Indeed, it is very difficult. I do not deny that. What you chose to do, however, is entirely up to you. I cannot tell you how to make this choice."
He paused for a moment. "If you decide to never make friends again at any of the places where we should move to in the future, you will be saving yourself from a certain amount of heartache. However, you will also be denying yourself much potential good. I am sure I need not list out all the potential things that can come from friendships, no matter how short. Then again, there is the possibility that even if you try, friendship will not lead to anything good at all but only hurt. Thus is true of any friendship, of course.
"I would suggest an attempt at friendships, and you should work to maintain the one you have with Norville despite the distance. After all, as long as no surprises happen, at most we shall move once every five years, perhaps longer. Ten years is the longest I feel comfortable staying anywhere, and it is a long time to stay in one place, and a long time to cultivate friendships. But, as I said, ultimately, the choice is yours."
He smiled briefly. "It may surprise you to know that I do, indeed, occasionally make friends, and it does sadden me to leave them behind. In fact, after the last one, I had sworn never to befriend a human again."
