In 1980, I was working as a temp in the offices of NBC. A TV screen hovered above my desk, playing the daytime shows. David Letterman was (briefly) on daytime then, until he landed his first late night gig two years later. His acerbic and witty brand of humor was clearly not meant for daytime. We are used to him now, and his style of humor, but he was an original. The thought of Larry "Bud" Melman still makes me laugh. He and his staff invented the Top 10 List. "Dave" has been part of my entire adult life, from age 22, just as Johnny Carson was part of my entire childhood. We aren't friends. We have never met. I have rarely even watched his show in recent years. But 34 years is a long time to remain a familiar presence, glowing pixels through the TV screen or emanating light from the laptop, 5 nights a week - a bastion of comfort in this fast-paced ever-changing world. So I will watch Dave's final show tomorrow night. And It will bring back a flood of memories from the past 34 years. And I will miss him.
