A lot of Millennial parents are -- paranoid. We have had neighbors exclaim that they don't want their children saying hi to us or they'll learn to talk to "strangers". Or a neighbor whose little boy played with my daughters for months, but when they moved the mother scowlingly rejected the idea of playdates because part of her goal in getting a bigger house was -- to put it in my words -- insulating him from other children. These tend to be the same parents who micromanage their children in other ways, like very limited diets and excessive summertime clothing, so, again, it seems like some form of paranoia.
