Things brought up by my children & discussed during our 20 minute car ride:
-Likelihood of another Earth-like planet
-Species of caterpillar that can survive almost any temperature on Earth
-Analysis of the difference between how Addison and his brother cope with boredom ("Asa gets physical, and I just sing.")
-Consciousness, our sense of "I", & the human soul
-Inevitability of the sun's demise
-The structural integrity of spheres
Oh, and Olive wanted to know "Why do grown ups always get dazed out when I talk?"
I need a nap.
