“Piglet noticed that even though he had a Very Small Heart, it could hold a rather large amount of Gratitude.”
[A.A. Milne, Winnie-the-Pooh]
Feeling gratitude and not expressing it is like wrapping a present and not giving it.
[William Arthur Ward]
I would maintain that thanks are the highest form of thought, and that gratitude is happiness doubled by wonder.
[Gilbert K. Chesterton]
