As the son of one, I can tell you...My father (COBE) is a full-time pioneer (has to be one right?).
When he returns home, it's grab something to eat...Mom watches TV if not studying (or doing both at the same time).
After eating, he's off to the Office to work on ...Kingdumb shit until 11pm or later. This is the case for all except maybe one or two days out of the week.
The "until 11pm or later" part that is. I mean...he does JW shit in the office EVERYDAY unless they're on vacation somewhere.
My mom goes to bed alone most nights and I'm sure wishes he'd spend more time with her. She probably wishes she never pressed him to become an Elder because he went full-speed ahead and never looked back. His position is his most prized possession. Even SHE's said that.
