Jiro, you shared a story about your dad, so I feel a little compelled to share this story with you. My Uncle Warren from Brooklyn, New York was in the Pearl Harbor attack. He was one of two survivors of an LST that was sunk. He had amnesia for about 6 years after the attack. My nana (grandmother) thought he had died. So did my great grandmother.
Anyways, when he had recall, he found his way home in Brooklyn with an orderly. No one knew his name, even himself, he just remembered how to get home. My nana saw him walking down the street as she was sitting on the front stoop. She ran inside to tell her mother. Her mother told her, "its not him sweetie, its just someone that looks like him ... " when he knocked on the door.
My great grandmother, whom I never met, fainted.
There was a high hatred of the Japanese amongst Americans of that era. My uncle was one of those Americans.
Well, eventually the next generation of children were born. My nana's sister (my aunt) had twin boys. One serves in the Army and is in Iraq, his brother married a woman from japan
Interesting no? My Uncle Warren had to swallow his old feelings of hurt to welcome her in the family.
