When children spend most of their waking hours only around those who are similar to them, they tend to believe that this environment represents the world.
OCCASIONALLY I get nostalgic about my school days and how different things were then. When I was growing up in a small town, my parents sent me to the local mission school because it was known for its high academic standards. The school was run by Catholic nuns and not many Muslim girls went there because some parents were concerned that their daughters might be “influenced”.
