First version:
"He turned away and went out. I watched the door close and listened to his steps going away. After a little while, I couldn't hear them but I kept on listening.
"Don't ask me why. I couldn't tell you."
"He turned and went out. I watched the door close and listened to his steps going away. Then I couldn't hear them, but I kept on listening anyway. As if he might come back and talk me out of it, as I hoped he would.
"But he didn't."
And the last one:
"He turned away and went out. I watched the door close and listened to his steps going away. After a little while, I couldn't hear them but I kept on listening.
"Don't ask me why. I couldn't tell you."
Second one:
"He turned and went out. I watched the door close and listened to his steps going away. Then I couldn't hear them, but I kept on listening anyway. As if he might come back and talk me out of it, as I hoped he would.
"But he didn't."
And the last one:
"He turned and walked across the floor and out. I watched the door close. I listened to his steps going away down the imitation marble corridor. After a while they got faint, then they got silent. I kept on listening anyway. What for? Did I want him to stop suddenly and turn and come back and talk me out of the way I felt? Well, he didn't. That was the last I saw of him.
I never saw any of them again - except the cops. No way has yet been invented to say goodbye to them."
"It's okay with me"
