I call my parents everything. Popdigr is Pop, sometimes Daddy (here,
almost everyone calls their dad Daddy, guys and gals, grown or not), when I was young, and needed money, I'd call on 'Daddy Warbucks'.
Momdigr is Mom. When I'd hit her up for cash it was 'Mother Dearest'.
Popdigr's parents were MaMa (not mama, but, Ma, twice) and PaPa (not papa, but Pa, twice), whereas Momdigr's were Grandma and Grandaddy.
I'm happy to not be a dad, daddy, pop, poppa, fahthuh, or Daddy-O.
