Each of us lives in accord with the myths which define our sense of being. Myths are more than history in that they grow from personal and shared memories and imagination. This is especially true of family myths.

I've been told that as a young man my Father had a fiery temper. Dad was 42 years of age when I was born and the man I knew was wise and mellow. The age at which memories were created also has a part in what one remembers. This spring I was surprised at the smallness of the house and farm where I was born and raised. As a child they were huge but of course I was much smaller then and size is a relative thing.
