Our is, and we like it.
Daughter just graduated from college with an honors degree in Comp Sci. Got a great offer to work at a major R&D facility near where we live. We asked her to stay at home. We get free house sitting, and she saves a lot of money. Its working out well. Then again, she is doing this by choice and it is beneficial to all of us.
I would like my daughter to stay at home when she graduates too, but it's not going to happen. We had my husband's son with us for years after he graduated and I hated it. He didn't contribute anything toward his stay there. I didn't want money, but I did want help around the house and a feeling that he was a part of the family. He now lives with his 87 year old grandmother and still doesn't help contribute--time or money. He's a moucher. I've told my daughter the same. She can stay but must be a part of the family. She wants to leave. She could save money to help buy her own place if she would. All kids are different.
