According to your experience, who is better groomed: a child who is born in Nigeria and spend some part of their childhood there before heading for the west or a child who is born and lived in the west for the whole of their childhood.

I know this can depend on the parenting and the individual child but just a general observation.

None. To my utmost surprise my cousins here in America are very nice cute children.

A child whose parents are loving and attentive is better groomed.
The society you live in cannot groom your child for you.
