I like what MWM said, too.
It is so tricky for adult kids to move home. Adults living in your home. Just thinking about the issues is a worry. It is difficult when rule-abiding adult relatives visit and stay a few days.
and a difficult child adult, where rules/guidelines/parameters have seldom, if ever. worked???
Not thinking I could do that. With our two easy child's, yes. With difficult child? naaaahhhhhh
