A Tap Along the Groove

Hot dog! A sudden little wiggle ran straight down to my toes! I blinked at the smooth, dark wood beneath me. Right beside my feet was a long, neat seam separating the floorboards. Full of curiosity, I lifted one heavy shoe and gently tapped the groove. Click-clack! The little sound echoed softly in the quiet night. My feet really move! I took one bouncy step forward along the line and paused, beaming at the vast room ahead.
