“But love is much like a dam; if you allow a tiny crack to form through which only a trickle of water can pass, that trickle will quickly bring down the whole structure and soon no one will be able to control the force of the current.”

“Love is much like a dam: If you allow a tiny crack to form through which only a trickle of water can pass, that trickle will quickly bring down the whole structure, and soon no one will be able to control the force and current.For when those walls come down, then love takes over, and it no longer matters what is possible or impossible; it doesn't even matter whether we can keep the loved one at our side. To love is to lose control.”

“Granny Weatherwax was often angry. She considered it one of her strong points. Genuine anger was one of the world's greatest creative forces. But you had to learn how to control it. That didn't mean you let it trickle away. It meant you dammed it, carefully, let it develop a working head, let it drown whole valleys of the mind and then, just when the whole structure was about to collapse, opened a tiny pipeline at the base and let the iron-hard stream of wrath power the turbines of revenge.”

“If you feed enough oats to the horse, some will pass through to feed the sparrows (referring to "trickle down" economics).”

“Trickle-down theory - the less than elegant metaphor that if one feeds the horse enough oats, some will pass through to the road for the sparrows.”

“Look! A trickle of water running through some dirt! I'd say our afternoon just got booked solid!”
