Water falling sounds like-- children giggling, people whispering, babbling, trickling. Spreading thirsty rumors throughout the mill, pushing public secrets thru the private pipes until-- Exposed! someone turned the screw, forced the flow and found them out, information leaking down, down and out the rusty spout, (mindless faucet) spilling careless splashing to the basin, the sink, I think,
sighs and pouts--and the water, reluctantly, finds it's way out.
