It is no tragedy to do ungrateful people favors, but it is unbearable to be indebted to a scoundrel.
Francois de La RochefoucauldNothing is so contagious as example; never was there any considerable good or ill done that does not produce its like. We imitate good actions through emulation, and had ones through a malignity in our nature, which shame conceals, and example sets at liberty.
