After Scout's first day of school, she wants to quit and be "home schooled" as Atticus had been. Atticus is adamant, however, that she receive a proper education at the local public school. He realizes that it may not be easy to convince Scout to return, so he devices a "compromise": He will continue to read to her each night without revealing this to Miss Caroline.

"... she never kissed a grown man before... what her papa do don't count." (Chapter 19)
