Mothers and Sons have a special relation. After the loss of their father, I was at a loss until I remember that my grandmother had lost her first born son  in the 1890s and dealt with grief.  Both stories are held together with fishing at streams. "I see her on the river, the boys crouched at her feet. The future is ahead of her and she is looking with pole in hand. Sons and streams.  This is something I know and she gives me strength. Is not our whole life a stream on which we drift?"
