What’s the nicest way to tell our neighbors that our son will not ever have a play date with their children?

Our next door neighbors are the grandparents of two boys who are our son’s age (5).They have custody of the boys because their parents are drug addicts. It’s quite obvious that they’re not psyched about raising more kids. We are constantly hearing them scream things at the boys like “Just shut the fuck up!” and “why are you so fucking stupid” and much much worse.The boys are absolutely obnoxious. They’re 5 & 6 years old and use racist and homophobic slurs. They’re extremely violent with each other and the only playing I ever see or hear them do is pretending to kill things.I know that it’s not the boy’s fault they’re being raised this way, and I do feel extremely bad for them. But that doesn’t change the fact that I don’t want my son playing with them.Recently the grandmother has been asking when we’re going to get the boys together to play EVERY time she sees one of us, which is very often. We’ve been dodging it with various excuses, but it’s getting very tiresome and I’d much rather find a way to politely decline our kids playing together. Plus it doesn’t seem like she’s going to give up any time soon, she’s been asking repeatedly for MONTHS. via /r/Parenting https://ift.tt/2lLF4BF
