Just know that your father will be missed terribly, especially anyone wandering about in the middle of the night. He was good company to those who don't sleep and you never had to worry where you stood with him.
A straight shooter and a gifted writer whose thoughts were above my pay grade some days. But, he was also down to earth and his tea and toast or nap time were just a small part of who he was.
I can only offer my heartfelt condolences, losing a parent is so very profound.
