Let it go. They checked, (they have to) they found nothing wrong.
Bad idea to get is a pissing contest with someone who buys tear gas and flash bang grenades by the shipping container full.
I’ve had tenants who were getting kicked out who made a claim to police regarding an older relative as a tool for retaliation.
Wellness check is step one.
Social services could easily come Monday, so have doctors records and visit information handy.
Be on your A game for a week.
If nobody shows past mid week it could be over.
Similar thing happened to my mom in January. We think she had a stroke - but it was never confirmed. She was disoriented (for the first time ever) and my sister went over and drove her to the Hospital where she was admitted for about a week. She lives alone and the doctor said she needed 24 hour care. A week after she was home, Welfare Services stopped by and interviewed her for 30-45 minutes to see if she was ok (she had 24 hour care). They said they’d be back frequently, but we never saw them again. She’s since moved into a senior center. I think they were just doing their job - my guess is there was some misunderstanding with the paramedics.
