Kieona: What's the point?

Recently, Kieona has taken to reasoning in a way that Mommy couldn't believe her ears. Once just a couple of weeks ago, probably in August when I told her to take her nap, Kieona just blurted out "What's the point, Mommy? I have to sleep at night." So do I laugh or do I cry? Smart, smart Kieona at 3 yrs old. So logical and so comical.
