Sure, the man might have "paid his dues" and was hard working back in the day, but what about lately?
In other words, I think some of his reputation for "hard work" might be resting on his laurels.
Why do I say that?
It's not exactly the hallmark of hard working to have *two children*. Especially two older kids, who take care of their own laundry, sweep the kitchen & living room, take care of the dishes, etc.
Sounds like mom & dad have plenty of free time. Speaking as a parent of 4 young children, I can say I'd have a lot more free time if I only had 2 and they were older!
And what are mom & dad doing with their free time? Playing around on their own computer/tablet/laptop, and other gadgets? There has to be a reason Hannah thinks she should be doing less work. Maybe the parents are engaging in a bit of "do as I say, not as I do."
We're not getting the whole story here.
