Thanks for the background of the story. So in essence, she didn’t get kick out of the house. I didn’t know about this story and the OP said she was kicked out.
You still didn’t really answer my question. Would you kick out your kids if they’re deadbeat? I know plenty of people who live with their parents until they get married and are not deadbeats. I also know plenty of people who got their college education covered by their parents. They’re not deadbeats either and they’re still quite close to their parents. Some even move back in with their parents till they got married to save for a house. So, I don’t see anything wrong with parents choosing to support their kids when they need help. Just like kids choosing to support their parents when they need help in their old age.
