As a kid, I had certain expectations of the world. For instance:
All children, except my siblings and friends, were brats. Still, it was important to be nice to overweight children and kids with glasses, because they were teased constantly and ruthlessly. The same applied to kids from divorced homes, because their lives were terrible.
All normal children attended public school and were Catholic. (Homeschooled Protestants like myself were weird.)
The entire purpose of college was to meet your future spouse.
Every ordinary child had an invisible friend. (I felt guilty that I didn’t.)
Someday, I was going to die.
