I have a grandfather whom I never met nor have I ever seen in a photograph. That's because he died in prison for having put a shotgun blast through my grandmother in a jealous rage that was witnessed by my father and several of his young siblings. My grandparents' names were assiduously scrubbed from the family lore in an effort to spare my orphaned father the shame and horror he struggled with on a daily basis from that life-altering event. That revisionist history stood for a very long time.
So, yes, show me that framed photograph so I can learn from it and deal with it on my own terms. You're not entitled to deny me the truth. No one is.
