I don't lose sleep over what I have done or have nightmares about it.
I saw him... at peace in my armchair. I remember wishing he could stay in peace like that forever. I had a feeling of easing his burden with my strength.
In the morning he was lying dead on one of the beds fully clothed. He was dead. I got the impression he wanted to go, and I must have killed him. I can't remember strangling him. I just sat there shocked.
