I've identified with Vulcans ever since the original Trek
was on NBC back in the '60s. I tend to be reserved and aloof, and I don't like to show emotion. I can also be a pedantic asshole sometimes.
Pretty much this. Well, I wasn't born yet when the original series was first on, but other than that... I've been called cold and unemotional, and on another message board people used to call me "Spock" (without even knowing I watched Star Trek) because of this tendency.
