And you know this how? Did you walk up and ask their "children"?
Our neighbors in CA, both RNs - one of their girls was tomboy and the other only liked dresses. One liked softball, one liked gymnastics. The other family I know had at least 8 foster/adopted kids with disabilities including hearing loss - which is how I met them. The kids all spoke English/signed and also spoke Spanish. They left California for the midwest to find better educational opportunities. So yes, I spent quite a few hours with these people.
