Leaves fall in the Fall.
Leaves flump in the Downtick.
Leaves flop in the Glide.
Leaves founder in the Comedown.
Leaves descend and drop in the Tumble.
Leaves nosedive and lurch in the Downflow.
Leaves pitch and capsize in the Forced Landing.
Leaves topple and cascade in the Gravitation.
Leaves abseil and rappel in the Descent.
Leaves coast and sideslip in the Downrush.
Leaves skid and avalanche in the Dropping.
Leaves swoop and plunge in the Coast.
Leaves settle and precipitate in the Cropper.
Leaves glissade in the Glissando.
. . . where's a rake when I need it?
