Rassenfrassen neighbors!

They're 3 and 5? I really hope that fence keeps them out. We already know that their parents are just awful.

You might want to get something into writing (I watch The People's Court every day!)
to their parents about your not wanting them over there unsupervised by a parent in case of an accident. After she doesn't come with them, I would then send something in writing to Children's Services and the head of your city's police, along with a copy of your letter to the mother. At least, if anything does happen, you might be covered
because you can show your written requests.

I really feel sorry for the kids, as I'm sure you do, but you're not their nanny.
