I was a neighbor of Judge Cusack for a number of years. For part of that time we were in the same apartment tier. Mail carriers sometimes mixed up our mail, and the first time I rang his bell to give him the misdelivered mail the Judge suggested that I just leave the mail at his door if it happened again. That worked out well; I could hop off the elevator at his floor, drop the mail at his door, and get back to the elevator before it had left the floor.
I might see him in the garage, on the street, or in the laundry room, and he always had a smile on his face and enough time for a pleasant conversation.
My condolences to the friend who shared some years of his life with him, and to all his family. May he rest in peace.
