Our policy is that this is their home and they're always welcome here. They do still ask if they can go X, let me know where they are and when they'll be home. Still have to follow house rules such as no drinking and driving, pick up after yourself etc and chores are the same as they always were.

When my husband and I moved in with my parents for a few months when he got out of the service, my parents would not take anything for rent, but we purchased all groceries, I did the cooking and cleaning. This was a very difficult situation for us because we'd be on our own for nearly 10 years by that time. There were times when we'd visit other family members out of town and decide to spend the weekend and it never occurred to me to call home (makes mental note to cut my kids some slack).
