Lightly come or lightly go:
Though thy heart presage thee woe,
Vales and many a wasted sun,
Oread let thy laughter run,
Till the irreverent mountain air
Ripple all thy flying hair.
Lightly, lightly — ever so:
Clouds that wrap the vales below
At the hour of evenstar
Lowliest attendants are;
Love and laughter song-confessed
When the heart is heaviest.
-- James Joyce, via Brain Pickings
