He taught us a lot about logic and emotion; more crucially still, the need to balance both in order to live well. Along with the rest of the Star Trek teamfamily, he taught us about tolerance -- not just of others, but of ourselves. He showed us glimpses, not just of one future, but of many futures. In doing these things, he left an imprint that will last as long as our culture does.
So I'm sorry he's left us -- though he has left quite a lot to us -- and I'm really going to miss that man. But on the other side...
Leonard Nimoy looks at the enormous mob burgeoning around The Great Con in the Sky. Two cloud buses have arrived simultaneously. One of them disgorges a flock of angels -- is that Metatron? -- while the other lets out a stream of tzadikim. On the front lawn, a circle of Summerlanders are spit-roasting an entire ox.
Leonard shakes his head and sneaks around back in search of an open window. Just as he is closing the window behind himself, a soft sound makes him whirl around. "Gene!" he cries gladly.
"Hello, old friend," says Gene Roddenberry as they hug. "Sorry about the crush out front. People are excited to see you."
Leonard raises an eyebrow. "Coming in the back way was a logical ruse," he says. "But what are you doing here?"
"Waiting for you," Gene replies. "Since you made your peace with old Spock, I figured you'd take the logical route. Come on, I'll show you where we stashed the secret Green Room. If we hurry, we can get there before Isaac Asimov eats all the cookies."
Grinning, Leonard drapes a long arm over Gene's shoulders and says, "Lead the way."
