They Tell You A Lot

Footprints in the snow
I know where you're going

Footprints in the snow
I know where you've been

Footprints in the snow
what size your foot is

Footprints in the snow
only knowledge within

Footprints in the snow
dark on the inside

Footprints in the snow
white on the outside

Footprints in the snow
i can't stop my shoe

from making
Footprints in the snow

Who made them, Who?
