All that we give is also given to us. But grumbling and grudging also attract their like to ourselves. If the person to whom we give a reward or gift receives it grudgingly and grumblingly, shall we give him more? And then, the fact that we do not give him more gives him still more to grumble about! But the person who is glad and thankful and appreciative of what is done for him, you think he is so good. It gives you such a feeling and such happiness to see him happy and appreciative and contented that he encourages you to do more, and it encourages others to do good also.
