I remember when I was young, and although it was some time after the original series had it's run, me and the kid across the street used to watch re-runs of the original series after school and then go outside and play Star Trek. He was always Kirk and I was always Spock. That got on my nerves a few times, but looking back on it now, I am honored that I tried to emulate him. I was sharing some good memories with my wife today during lunch of those after school re-creations. I got a good laugh out of some of it and I hope Mr. Nimoy was listening on and enjoyed it too.
I hope his family can rest somewhat easily knowing he is loved by many who never got to meet him.
"We are assembled here today to pay final respects to our honored dead. And yet it should be noted, in the midst of our sorrow, this death takes place in the shadow of new life, the sunrise of a new world; a world that our beloved comrade gave his life to protect and nourish. He did not feel this sacrifice a vain or empty one, and we will not debate his profound wisdom at these proceedings. Of my friend, I can only say this: Of all the souls I have encountered in my travels, his was the most.... human."
Edit: I just read about it after you mentioned it. I guess it sucks that he didn't go, but if he was honoring a commitment, I have to agree that he'd be just as blasted for leaving or not honoring it if he decided to go to the funeral instead. I think he knew he was going to get it either way, so he decided to put himself out there and deal with it head on.
We have lost alot of stars and famous people from our childhood....but Robin Williams and Leonard Nimoy have hit the hardest so far. I have never known Sci Fi without Spock. Nor would have I known humor if it wasn't for Mork.
