...ah, so "visiting with just our granddaughter" means they only come for her and (try to) ignore the other children? Wow. How very "kind, soft, well-mannered" of them, they sure set a great example.

"The boy is destructive and touches and picks up things inside and outside the house with the intention of destroying or breaking them." How do they know that is his intention?

These are some awful, awful people, and I like the answer given.
