Sugar lay on his cot, and sensed her, half way around the world, struggling over a blank paper, missing him, but not knowing how to express it. This was good, and, hopefully, the reason for her letters not coming. Helen would eventually apologize to him for not writing, and he would forgive her. He would be angry at her for a while, and then it would be okay.
Sometimes, he imagined himself forgotten, and it would simmer until he wanted to call her on the satellite phone, tell her in very few words how much pain she caused him, and then hang up and get killed.
He never called, and never got killed either.
