and he just keeps going

Today in the car Bella asked me where Everett is.  I reminded her that it's the city we live in, to which Isaac said, "have mercy, I thought we were in Washington!"  I began to explain the concept of city, county, state, country, continent, hemisphere, planet, universe......... Which caused Isaac to ask, "what's a planet? Does it have wings?"  Wow.  On a brighter note, Nahshon noted to me today that the feet on a tree frog look a bit like suction cups.  He gives me hope........
