Man. Man. Man. Reminds me a bit of when there's an illness in a family.You dont/cant talk about it because it's embarrassing. It causes problems for you in school because you're up too late trying to help. And kids get fucking weird about Just Literally Anything unusual.
And the adults who should be helping have their own things keeping them busy, and it's so, so tempting to let a responsible kid help. maybe you don't even realize how bad its getting for both of them, cause a Good Kid doesn't want to explain they can't handle it, either.
And who's around to help their grandma with the kids.....?
And then he's going to 'fail' again.
