Yesterday and today, I had to explain inertia to my boys for our science lesson. Being a rather resistant student when it came to math and science, I am surprised that in needing to teach something I forced myself to misunderstand, I actually "get it." At least enough to explain why hard boiled eggs spin. At least enough to realize how much I resist change, that an inert life sounds inviting sometimes, that the push and pull of life often causes more friction even to a damaging degree. But if something soothing is added to my life--a smile, a kind word, a tender touch--the friction lessens much like oil to shifts and gears. It reminds me that an inert life is a dull life, and learning how to enjoy life's spin makes all the doing worth while.
