I've got a lot of memories of Mr. Spock. Played by Leonard Nimoy in the iconic Star Trek series. I grew up watching him, and enjoying his character. While I liked Scotty, I think Spock might have been my favorite of the main characters.
He died today at 83, which I should have expected at some point, but after seeing him in the latest Star Trek movies, I thought he might live for quite some time. It's a huge reminder of my own mortality as I see more and more people I've known, or enjoyed, for most of my life.
A sad day indeed, but I'll have many, many fond memories of Mr. Nimoy in the years to come.
