A Vulcan Civilian can come into mane different shapes. Lets take Spock, a chief science officer under Captain James T. Kirk of the USS Enterprise, known for his great intellect and in his later years from spending time with his fellow human friends. One thing many files about Spock neglect to tell is that he is a half human Vulcan as Sarek ( Spocks Father ) loved a human. Spock had an amazing grasp on instruments, and when in the episode Amok Time he invites Kirk and McCoy the chief doctor aboard the USS Enterprise at the time to his wedding ritual. But part of his wedding ritual Spock tries to kill Kirk. It is truly showing how Vulcans can change over time, at least they aren't Romulans .
