Another thing that Ann Rand gets wrong in her vampire novels is the implicit message for young people that if you are ambitious and talented a la Roark, then older people will somehow be put off by you.

Now that I am a generation older I can say the opposite is the case.

It is one of the great joys to have friends who are younger who simply don't have the life data to make certain decisions. All you have to do is give them information and they're off to the races. The cost/benefit could not be higher.
