Characters
A man provides. And he does it even when he’s not appreciated, or respected, or even loved. He simply bears up and he does it. Because he’s a man.

Our reading
An editorial interpretation.
The speaker defines manhood as steady provision that continues without thanks, respect, or even affection. On this view, endurance is the point: he quietly carries the burden and keeps giving because duty demands it. It is a stoic, somewhat grim ideal, stated as the speaker's belief.
