Adult son at home
There are those parents who firmly believe that once your child gets to a certain age, they should get their own place or start paying rent to you. There are other parents who prefer to think of their responsibility as permanent, even when their child is 35 and still expecting you to do their washing.
While I don’t think kids should get to stay at home indefinitely without contributing, I do think that kicking out your son when you don’t know if he has anywhere to go, because you need a nursery is a bit much. If it was something that she was that worried about, maybe she should have started dropping hints sooner.
