Pa had been clear on all points. He always said, “If a path ain’t got no heart, you must not follow it, not for any reason—but if it does got heart, then you’d best oblige yourself. On account of doin’ good ain’t got no end. Like a pebble thrown in a pond, one kind act ripples outward in all directions. It affects others—for the betterment. How far the ripple may travel—no one can rightly say."
