From Dreamdarkers:

When I moved to Kingswell and began work to make Carr Beholden livable not just for me but for my parents as well, I wished to separate myself from everything my life had been while married.  Sure, happiness and fulfillment defined those years, but afterward…  Afterward.  What a cruel word.  Defined as that occurring after something else, it coldly proclaimed the meaning of my new life.  Dave Lloyd came in two flavors the three doctors could not fix.  There was before death and after death.  That equated to ‘B.D.’ and ‘A.D.’ for those writing in shorthand, thank you very much.  I knew the B.D. years represented the most wonderful time in my life.  And A.D.?  The worst.
