The value of life deepens incalculably with the privileges of travel.
The indifference, callousness and contempt that so many people exhibit toward animals is evil first because it results in great suffering in animals, and second because it results in an incalculably great impoverishment of the human spirit.
With regard to manner, be careful to speak in a soft, tender, kind and loving way. Even when you have occasion to rebuke, be careful to do it with manifest kindness. The effect will be incalculably better.
