She’s been ignoring his bad behavior for 30 years, and look where that got her.

There’s something kind of despicable about a fully grown adult who is perfectly capable of working and supporting themself deciding that they’d rather mooch off of their aging parents. If you’ve never known someone like this, you might think this is a bit of an exaggeration. Sure, there are adult children who live at home with their parents, but most of them are at least contributing to bills and groceries, or they’re saving aggressively so they can afford to move into their own place. There are millions of adults around the world doing just that, and in some cultures it’s encouraged, but there’s a big difference between that and being a mooch. 

If someone has no shame, they will have no problem taking up space and being disruptive in a home that they don’t even pay to stay in. They won’t have any trouble milking their parents for all they have because they’re too lazy to work. The only way to make these people change is to stop enabling them. That can be challenging when their parents’ enabling is the reason they’re like this in the first place.
