Yeah, some people ...
At least you can't blame yourself for not trying.
When I was doing research on the fightings in the Wiltz area in December 44 and January 45, I tried to get in touch with Veterans of the various units involved.
After trying and searching, I finally found a Veteran of the 447th AAA AW Battalion who might have the answers to some questions I had.
I wrote him, but my letter was returned .... below, in a corner of my letter, he had written "Sorry, I do not wish to remember this.". 
Although I can understand his reaction (he might have seen too much horror during that time), I felt let down big time as I never found another Veteran from that unit.
So, in a way, I can understand you.
Oh well, some you win, some you lose, I guess.
