A family member "offered" to move back home, and bring his girl friend. They acted like they were doing the parents (late 60-ish) a favor. This same couple had already stolen the mom's I.D. and helped themselves to the parents' investment account -- over $12,000. The son sells recreational drugs for a living and wouldn't think twice about doing drugs out of the parents' home. His driver's license was revoked because he didn't pay child support and the state won't allow him to get a new license til he pays long-overdue support. (Kids are grown now and don't want anything to do with him.) If the derelict son moved home he'd happily help himself to his parents' cars.
Um no, that just isn't gonna happen.
