“Gratitude is a sign of maturity...Where there is appreciation: there is also courtesy and concern for the rights and property of others.”

“The most exquisite pleasure is giving pleasure to others.”

“I would maintain that thanks are the highest form of thought; and that gratitude is happiness doubled by wonder.”
