Old guy I once met would not recount any experiences he had being a "guest" of the Japanese in Malaya, and then later in Singapore. He said it was too painful to tell, and that if he was asked, he would just say... "yep, I was there, now I am here, lots ar'nt." I couldn't get him to say much else without tears running down his cheeks. That was 60-odd years after??
God knows what he went through there to make him so emotional all that time afterwards.
What he WOULD tell me, was that there were 8 thousand p.o.w's taken by the Japanese in that particular theatre of operation, only 900-odd came home afterweards, most died from dysentry, malaria, or simply worked to death. His total hatred of the Japanese has stayed to this day, and no amount of "forgive and forget" will wash with him. He got physically angry when you mention what an advanced nation Japan have become, he wonders why America only dropped 2 atomic bombs, and says they should have finished the job properly. quite a bitter man, but you have to understand why.
And we think we've got it hard sometimes??
