I would probably suck the blood of the ones I hate or if the one I love wants to be with me forever and they're a human I would drink some of their blood as I change them into the night walker I am. I may do other things like LeStat in Gueen of the Damned but I would most likely just be more of a human at night with my forever love.
I would suck on the blood of those who I love, because it would be a pure feeling. Since I found my forever love I would change him as well if he wanted me too, and like Klaus from the TVD! said I would love to see all the Art, hear all the Music & Read all the Books of this world and I will have enough time to do it.
i would clean my hometown out of scums..rapers, thugs etc by sucking em dry. It sure would become the safest place in the world...so id have to move and travel from town to town and go on with the cleanup.
