"But, to make them blessings, you must act your part well; for they may, by your neglect, your ill-treatment, your evil example, be made to be the _contrary of blessings_; instead of pleasure, they may bring you pain; instead of making your heart glad, the sight of them may make it sorrowful; instead of being the staff of your old age, they may bring your gray hairs in grief to the grave."
