Most People return small Favors, acknowledge middling ones, and repay great ones with Ingratitude -
Benjamin Franklin 1751
Old Ben knew that folks hate to eat humble pie. Indeed, it's easy to proclaim gratitude for generalities. I'm grateful for liberty, nature, and a blanket. Depending on the situation, it's tougher to be grateful to someone, especially if you caused your own grief. Best to swallow the pride, say thanks, and move on.
