Fleet as an arrow
Flitted like a sylph on wings
Flowers as soft as thoughts of budding love
Fluent as a rill, that wanders silver-footed down a hill
Fluid as thought
Fluttered like gilded butterflies in giddy mazes
Fragile as a spider's web
Free as the air, from zone to zone I flew
Free as the winds that caress
Fresh and unworn as the sea that breaks languidly beside them
