A Tiny Golden Trail

I slid quietly off the soft grey cushion onto the wooden floor... it felt so smooth under my feet. Right beneath the sofa edge, a tiny brown ant was marching across a patch of morning sunlight, carrying a golden crumb twice its size! I knelt down, pressing my plush paws gently against the floorboards so I wouldn't disturb it. When it paused near a fallen thread, I held my breath... and watched it find a secret route underneath the dark skirting board. Where do you think it's taking that feast?
