The Silent Observer

We were driving in the car the other day and my son said from the back seat, "I know how to count by 20s." He then rattled off 20 - 200 without skipping a number.  I asked him if he learned it at school and he said, "No, I just looked on the dashboard and saw 20, 40, 60 and just kept going.  He was looking at my speedometer.  I am amazed at the observations and connections he makes.  He can observe his surroundings in a way that I never could - more in depth, more aware.
