Self-love, my friend, bewitches parents to give too much indulgence to infantine foibles;- the constant cry is, "Poor little soul, it knows no better!" If it swears, that's a sign of wit and spirit; if it fibs, it's so cunning and comical; if it steals, 'tis only a paw trick- and the mother exultingly cries, "My Jacky is so sharp, we can keep nothing from him!"

(from vol 1, letter 28: 4 Oct 1775, to Miss L___).
