low gravity

The children were outside discovering
what Northern children have learned
afresh after every snowfall: snow
creates low gravity. Any of them
could express the formula kinetically
by leaping onto a pile of the stuff:
the soft landing demonstrates the principle
that gravity is very grave until
you take a run at a honkin’ big pile of it.
Then hear the giggles and the sillies
the happen as a group of children roll
and tumble in the excitement of
so much fun and so little gravity.
This surprises Southerners who have never
seen nor heard such levity. And how
astonished they are to see children drift
up, let go of laws and rules and dance
with the snow, where joy lofts them.
