In Nagasaki, there is one time period that ended at two minutes past eleven, and another moving ahead in a present progressive tense that began at two minutes past eleven, August 9, 1945.
Forty some years after the shift, people were made aware that part of the present progressive tense is the Nagasaki of people who were unable to hear the bomb's bang.
Much has been told and written of the experiences of the bombing victims with normal hearing. They have come to be well known.
Deaf and dumb victims, though, were passed by, a forgotten existence sunk in an abyss of silence.
