Those who only knew Susan Casper in her later years, have no idea what a mischievous scamp she was in her younger years.
I vividly remember walking down a hotel corridor in the early hours of the morning with Susan on our ways to our respective rooms. This hotel had a short-lived innovation: In place of key or keycard locks, it had punch pad locks. You chose your own four-digit number code. And of course this was a science fiction convention.
So Susan stopped at every door and tapped in 2001, 1984, and 1138. It is possible that alcohol was involved in her decision to do so.
Down the hall we sauntered, leaving half the doors behind us open.
