You don't know the first thing about OP, other than that he's trying to help out his dad.
Maybe his father didn't want to worry his family, and had been keeping it to himself. I have no idea, and neither do you; you just chose to assume the worst about someone you don't know.
Thank you; roughly accurate.
> you just chose to assume the worst
I did no such thing. My assumption was that OP, like most of us, dedicates most of his life to work. That's not a character judgment and it's not "the worst". It's normal.
In the absence of work he was able to help his dad, presumeably because he had more time. The "sad" part isn't OP, it's the fact that work demands so much.
