"It's David," the principal said. She was a woman of forty. "The child you are homeschooling. Your son Jamie brought him to school for the day.
"yes, to see how he did..."
"And I am afraid he did not do well. On the playground he bit another child.
"He very nearly drew blood."
"We see this in home-schooled children, Mrs. Kendall. They severely lack socialization skills and inner controls. There is no substitute for daily school environment with peers."
By the way, David the child in question is a transgenic chimp who is being passed off as a human child with Gandler-Kreukheim syndrome (which is a totally made up syndrome to explain David's appearance).
