A Tap on the Wood

Whoa! My joints loosened up all at once! I stood right here on these polished wooden planks, blinking into the dim evening light. My fingers twitched, and when I took a quick test step forward, my plastic foot clicked against the wood. Right behind me sat a white plastic bucket with a thin handle. I reached out, gave the smooth rim of the bucket a solid tap, and heard that nice hollow ring. Hey, I can actually move on my own!
