Dear Queenie,
My girlfriend has 2 grownup children who still live with her and she supports them and they don’t even try to move out or live on their own.
Queenie, how can I persuade her that they need to do learn to do better?—Worried boyfriend
Dear Boyfriend,
Ask your girlfriend who will take care of her if (when) she is no longer able to take care of herself, and what will become of her children if (when) she is no longer able (or there) to support and take care of them. These are matters to which she should give some serious thought.
