Like most people old enough to remember the 1970’s and 80’s, my first memories of Robin Williams were of his role in Mork & Mindy. I loved the show; my favorite episode was the one where Mork, through the use of over-the-counter cold medication, accidentally shrank himself out of our universe and into a parallel one. To a nine-year-old, this was mind-ripping stuff.
Perhaps they talked about it all day long, and Williams got so sick of it, he had to find a permanent way out. I don’t know. Just don’t sweep it under the rug. Such concealed monsters don’t stay under there, and they don’t get smaller from concealment: quite the opposite. They tend to take over the whole house.
