Socialization is an issue because, depending on the size of the community you interacted with and how integrated your parents let you be with the rest of America, many of us who were more sheltered are literally from a different culture that people who live in the same country. I have worked long and hard to be able to socialize with people from ‘Regular’ America, and I still, nearly 20 years after I graduated high school, and more easily socialize with people from a Midwestern conservative homeschooled background.
I sometimes tell people I grew up the in the same geography as you, but not the same place.
