My MIL (retired) lives a couple streets away from us, a ten minute walk. Her neighbors are on the board of a wonderful school we'd love our daughter to get into (it's supposedly by lottery but we don't know if that's truly how it's done behind the scenes)
The family has five kids and we have reasons to be concerned for their safety. Three weeks ago they had a fire and all the kids were home alone (oldest is 8, youngest is 1), they barely escaped without serious lung damage because a contractor working on a nearby house noticed smoke and got them out.
This week, the mom left the youngest in front of the house on the driveway to crawl around and went back inside for 20 minutes. The other kids started yelling for her when the baby crawled out into the street.
If we call in to social services, they may know and keep our daughter from getting into the good school, but we also don't want something awful to happen to the kids.
