For six months, I let my son and daughter-in-law live in my coastal Maine home for free while they waited for their new house to be finished.

For six months, I allowed my son and his wife to live in my home on the Maine coast without paying me anything.
No rent.

No utilities.

Not even grocery money.

Then one Tuesday morning, my daughter-in-law walked into my kitchen, checked the time on her phone, and informed me that I needed to leave.
