Gratitude is rather the offspring of a negative generousity of character, delicate sensitivity to least kindness received. Gratitude is of three types:- 1,gratitude in thought or a spirit of gratitude which is the foundation of the rest. 2.gratitude in word which must be informed by the inner spirit, lest it should generate into mere lip-virtue. 3.gratitude in deed is the test of the sincerity of ur words.
