Let the children be free; encourage them; let them run outside when it is raining;
let them remove their shoes when they find a puddle of water; and, when the grass of the meadows
is damp with dew, let them run on it and trample it with their bare feet; let them rest peacefully
when a tree invites them to sleep beneath its shade; let them shout and laugh when the sun wakes them
in the morning as it wakes every living creature that divides its day between walking and sleeping.
