Our 6-year-old surprised me last night. My wife and I were talking in the front seat about allegations that a particular presidential candidate doesn't like Jews. Our daughter asked why so-and-so doesn't like Jews. Seeking to avoid that kind of issue with her (at least while driving a car and not really able to discuss it), I said that we were just joking.
"I know you're not joking because mommy said that Papa [her grandfather] said that."
Oops. Smart kid. Now what do we do? :-)
