Recently my sister shared with me a stack of letters sealed in a plastic zip-locked bag she had found amongst my mom’s possessions.  They were love letters from my Father written around 1952 in the year before they were married. The letters reveal sides of my father I did not know. Kate Murphy’s new book, You’re not Listening:  What you’re missing and why it matters illuminated how "closeness communication bias" may have prevented me from learning more about this side of my dad while he was still with us.
