I was proud that I knew the answer, "Nine!"
He corrected me gently, "Nope, if one sheep gets out they all follow. The answer is zero."
We, like sheep, follow others to our own destruction. We look for greener pastures, even when we have all we need. We butt and push other sheep in our efforts to get what we want for ourselves. We tromp mud into clear streams of water, in order to get there ahead of other sheep. Sheep are harmless to other creatures but seem to have a knack for bullying each other and leading other sheep astray.
