Here is a small fraction of the questions Lucy asked me on the way home from Target (a ten-minute ride) (and in no apparent order or relation to each other):
"Mom, why do you hate red ants and black ants? Are they your fierce enemies?"
"Why can't the sidewalk be the street and the street be the sidewalk? Then we could always walk in the street."
"Are vultures ravens? Are all ravens bad or are some good?"
"When you're dead and someone pulls your hair, does it hurt?"
