We're living in an age where offspring aren't considered adults until they're in their 30s so I think what your friend is doing is part of this new trend. I agree it's a problem, but today's parents are so protective of even young adults that the poor kids are ending up emotionally handicapped. I don't know what the answer is other than to realize this is a trend that is going to lead to lots of issues in the future as children aren't allowed to grow up and make a life for themselves.
