Everyone has such long and detailed stories. Mine is pretty short, while my vampire's been around quite long.
My main vampire (which I'm going to make a grand master vampire), is Alexandra af Varg. She's about 1000 years old and from the Viking era. So, she's been through a lot during her life. She's also getting a bit cynical and bored. She mostly considers other sims as a source of food (and always drinks deeply without guilt), she's a loner, and she doesn't find humans very interesting in general. I thought about giving her the gloomy trait, but instead I decided to eventually give her the eternal sadness -weakness. So lately she's again found more interest in her long life by moving into a penthouse in San Myshuno and taking care of fresh teen vampire Chloe Fox that one of her friends accidentally turned (my vampires have an ethical code not to turn anyone younger than young adult). The friend died in a sun related accident, so now Alexandra has to teach Chloe to be a vampire.
So, Chloe was only recently turned (which happened in Bridgeport, because that's where Alexandra lived the last time I played with her in TS3). While she kind of considers her forever life cool, she still has trouble drinking from other sims. She prefers plasma packs, and every time she drinks from a sim, she likes to ask for a permission first. Unfortunately, not everyone gives her a permission, and plasma packs are not always enough, so she's had to compel sims for a drink a few times. But she's never drank deeply from anyone.
I made Chloe look very young, because I will turn her into a young adult soon (as soon as she becomes an A student), and I want her to still look kind of teen. She has the klepto trait, and I'm thinking of putting her on the criminal career. Alexandra doesn't have a job. She paints to make some money, but she has enough saved from all the time she's lived (I used cheats).
