The original Star Trek series was on our CRT TVs when I was 11-13. I was skinny, geeky, a social misfit, and I got straight As. I identified with Spock, what could be more logical? But he could do two things I could not: render people unconscious by putting his hand on their necks, and raise his eyebrow to show that his logical brain was processing. I calculated the illogic of trying to learn a Vulcan neck pinch. However, I could learn to raise an eyebrow.
Thus came many nights lying in bed, training my left eyebrow to stay still while I raised my right. Good thing it was dark and I was alone, else my older brother would have laughed or my mom would have called a doctor. To this day, I can raise my right eyebrow, but not my left. One eyebrow is sufficient to silently externalize my logical thought process. Two would be illogical.
My character Cal “The Intellectual” Critbert thinks like Spock, fights like Batman, and writes like Roger Ebert. The Spock part came first. Thank you, Leonard. I shall keep a small part of Spock alive.
