Child:  It would be fun to live in a house on the water, you could have a diving board where you could jump into the ocean.
Parent: Maybe someday when you're older you can live in one.
Child: But those houses won't be there then, it'll be the Modern World.
Parent:  What will the Modern World be like?
Child:  There will be hovercraft cars that don't run on gasoline, floating homes, houses with rockets coming out of them...
Parent:  Anything else?
Child:  Well, maybe the houses would stay the same, there'll just be new cars.
Parent:  Hovercraft cars?
Child:  And podracers.  But they won't run on gasoline.  They'll run on futuristicky stuff.
Parent:  Looking forward to it.
